EMC <str<strong>on</strong>g>2007</str<strong>on</strong>g> ADVANCE PROGRAM 41Development of a Maritime Electr<strong>on</strong>ic Warfare and SensorSystems EMI Mathematical Assessment CapabilityGiuseppina Dall’Armi-Stoks, DSTO; Guy Morris, N/A; and Annie Yau,N/AElectr<strong>on</strong>ic Warfare and Sensor (EW&S) Systems have to meet theiroperati<strong>on</strong>al capability in a maritime envir<strong>on</strong>ment. However, withthe ever increasing number of EW&S systems being fitted <strong>on</strong>boardmaritime platforms, and the reality that maritime platforms arebeing required to operate jointly, the likelihood of adverse <strong>electromagnetic</strong>interference (EMI) between EW&S systems is prominent.Investigating EW&S systems’ <strong>electromagnetic</strong> <strong>compatibility</strong> (EMC)can be an extremely complex problem. If EW&S system EMC is notaddressed and managed in a correct procedure, the soluti<strong>on</strong>s to minimizeEMI problems can be expensive and more importantly canaffect the operati<strong>on</strong>al capability of the systems. What has been recommended,by many in the EMC community, as a means of managingthe complexity of systems’ <strong>electromagnetic</strong> interference and/or<strong>electromagnetic</strong> <strong>compatibility</strong> (EMI/EMC) problems, is that theEMI/EMC must be assessed at the planning, designing and development,installati<strong>on</strong>, and/or operati<strong>on</strong> of electrical and electr<strong>on</strong>icequipment stages, each governed by an EMI c<strong>on</strong>trol plan.EMC Analysis for Sustainer Electric Propulsi<strong>on</strong>s and DeepSpace Communicati<strong>on</strong> SystemsNikolay Vazhenin; Andrey Plokhikh; Alexey Volkovsky; and GalinaSoganova, — RIAMEA general soluti<strong>on</strong> for the problem of EMC calculati<strong>on</strong> as applied to thesustainer electric propulsi<strong>on</strong> (EP) in rockets and deep-space radio communicati<strong>on</strong>systems is c<strong>on</strong>sidered in its classical statement. EP isdescribed as a source of unintended noise of artificial origin of the whiteGaussian noise type with the known spectral characteristics of radiati<strong>on</strong>.An <strong>on</strong>board receiver of the deepspace communicati<strong>on</strong> radio link is c<strong>on</strong>sideredas the receptor, the noise susceptibility of which is assessed bythe variati<strong>on</strong> of the radio link quality parameters – communicati<strong>on</strong>range and informati<strong>on</strong> rate. The calculati<strong>on</strong> results for the EP emissi<strong>on</strong>susceptibility of both informati<strong>on</strong> channel and phase synchr<strong>on</strong>izati<strong>on</strong>channel of the deep space communicati<strong>on</strong> radio link designed for aspacecraft in the orbit of Mars are presented. Recommendati<strong>on</strong>s aregiven for securing EP EMC with the <strong>on</strong>board systems of a spacecraft.Effective Technique for System Level Predicti<strong>on</strong> of theRadiated Emissi<strong>on</strong>s of Electr<strong>on</strong>ic Devices and Cablesinside Satellites from Unit Level MeasurementsFrancisco Saez de Adana; Manuel Felipe Cátedra; and Jose Manuel Gomez,— Universidad de Alcala; and Raj Mittra, Pennsylvania State UniversityA method to predict the <strong>electromagnetic</strong> emissi<strong>on</strong>s from unknownelectr<strong>on</strong>ic devices and cables at the system level is presented in thispaper. The method is based <strong>on</strong> measurements at the unit level,equivalent source decompositi<strong>on</strong>, and numerical <strong>electromagnetic</strong>simulati<strong>on</strong> of the integrated system. The approach is also valid forthe analysis of cables and c<strong>on</strong>ductors carrying electrical currents fromthe interior to the exterior of the measurement surface (Huygen’s surface)and is useful for the predicti<strong>on</strong> of the <strong>electromagnetic</strong> <strong>compatibility</strong>characteristics of electr<strong>on</strong>ic devices inside satellites.POSTER SESSION 02: PCB AND IC EMCEffectiveness of PCB Simulati<strong>on</strong> in Teaching High-SpeedDigital DesignJianjian S<strong>on</strong>g; Edward Wheeler; and Keith Hoover, — Rose-HulmanInstitute of TechnologySignal integrity for high-speed digital design at the printed-circuit board(PCB) level is an issue of increasing importance in electr<strong>on</strong>ic design thatrequires coverage in more undergraduate classes. This paper describeshow simulati<strong>on</strong> tools offer an ec<strong>on</strong>omical alternative to hardware-basedexperiments in undergraduate courses in high speed design. A simulati<strong>on</strong>tool, Hyperlynx, has been used in our high-speed digital design classto help students understand fundamental c<strong>on</strong>cepts and ideas in signalintegrity as well as to experiment with different techniques for maintainingsignal integrity in a PCB design. We present examples in whichtraditi<strong>on</strong>al approaches employing <strong>on</strong>ly closed-form expressi<strong>on</strong>s can beeffectively supplemented with simulati<strong>on</strong> to help students gain a deeperunderstanding of basic c<strong>on</strong>cepts such as time-of-flight, parasitic parameters,n<strong>on</strong>linear driver and receiver models, characteristic impedance, perunitlengthparameters, terminati<strong>on</strong> techniques, and crosstalk.Transmissi<strong>on</strong> Line Attenuati<strong>on</strong>-Impedance Realistic CornerModeling by Scaled-Down Tolerence Boundary ScanZhaoqing Chen, IBM Corprati<strong>on</strong>This paper discusses a method to generate transmissi<strong>on</strong> line attenuati<strong>on</strong>impedancerealistic corner models by a scaled-down tolerance boundaryscan. Based <strong>on</strong> nominal and tolerance specificati<strong>on</strong>s of the transmissi<strong>on</strong>line physical and geometric parameters, the scaled-down toleranceboundary scan is used to find the realistic corners in the attenuati<strong>on</strong>impedancespace. The tolerance scaling factor is determined or verifiedby comparing the derived corners with the attenuati<strong>on</strong>-impedance distributi<strong>on</strong>by M<strong>on</strong>te Carlo statistical <strong>electromagnetic</strong> simulati<strong>on</strong>s. Thisscaling factor can be used for similar structures in future applicati<strong>on</strong>s.The system eye diagrams based <strong>on</strong> different bounding models are shown.Impact of Linear Regulator Topology <strong>on</strong> Integrated CircuitEmissi<strong>on</strong>sKevin Lavery, Texas InstrumentsThe type of linear, <strong>on</strong>-chip voltage regulator is important to themeasured emissi<strong>on</strong>s from a device. A p-channel VREG is foundsuperior to an n-channel VREG in terms of suppressing emissi<strong>on</strong>s.Degree of Unbalance about Earth and Radiated Emissi<strong>on</strong> ofDifferential Type Microstrip Line in GHz BandMasahiro Shiota; Kiyotaka Matsubara; and Masamitsu Tokuda, —Musashi Institute of Technology; and Chiharu Miyazaki, MitsubishiElectric Corporati<strong>on</strong>Balance-unbalance c<strong>on</strong>versi<strong>on</strong> factors and radiated emissi<strong>on</strong>s from differentialtype microstrip lines (DML) have not been examined in thefrequency range above 1 GHz, because it is difficult to obtain the balunthat can be used in GHz band. In this paper, we tried to measure themin the frequency range above 1 GHz by using a mode analysis functi<strong>on</strong>of a network analyzer instead of the balun, and compared the measurementswith the calculated values by using the 4-terminal pair networkschain matrix theory. The comparis<strong>on</strong> results c<strong>on</strong>firmed that this calculati<strong>on</strong>method is effective in the frequency range above 1 GHz.A Scalable Model of Board to FPC Interc<strong>on</strong>nect UsingNeural NetworksHo<strong>on</strong> Hwangbo, Sungkyunkwan UniversityIn this paper, I propose the equivalent circuit model which includes theboard to flexible printed circuit (FPC) c<strong>on</strong>nector transiti<strong>on</strong> regi<strong>on</strong> andthe FPC c<strong>on</strong>nector to FPC cable transiti<strong>on</strong> regi<strong>on</strong>. Full wave simulati<strong>on</strong>sof the FPC interfaces are performed and the s-parameters of the simulatorsare compared to those of the vector network analyzer (VNA) measurements.The simulati<strong>on</strong> shows very similar s-parameters compared tothe VNA measurements verifying it as the reference tool for the equiva-©<str<strong>on</strong>g>2007</str<strong>on</strong>g> IEEE www.emc<str<strong>on</strong>g>2007</str<strong>on</strong>g>.org
