Over the past 10 years it has provided seed moneyfor the establishment of eight courses in the basic principles of electromagneticcompatibility at academic institutions on two continents.All past recipients were surveyed, and the collected data wasused to assess the impact and exceptional return on investment of theprogram. Brief descriptions of some of the experiments developed arealso included.A Historical Perspective of System-Level TDFD EME SimulationRodney Perala, Electro Magnetic Applications, Inc.Computational electromagnetics (CEM) and particularly the timedomainfinite-difference method (TDFD), began to be used for system-levelsimulations of electromagnetic effects (EME) in the 1970s.From that time until now, there have been dramatic advances resultingin large capability growth with simultaneous reductions in computingcost. The net result is that the TDFD method can form thecore of a powerful simulation capability, useful for virtual EME system-levelverification and demonstration.EMC Absorbers Through the Years with Respect to the NewSite Validation Procedure in the Frequency Range from 1 to18 GHz — A Practical ApproachFriedrich-Wilhelm Trautnitz, Albatross Projects GmbHThis paper describes the development of EMC absorbers and EMCchambers until today. The first anechoic chamber in Europe was builtin the mid sixties. Due to the fact that absorber chambers were notnecessary in the early sixties, EMC measurements were easily possibleon open area test sites (OATS). This project was for many years theonly EMC chamber in Europe. The market for EMC chambersincreased with increasing radio services because of ambient noise. Inthe mid eighties the market for EMC chambers again awoke. Thetechnical requirement for EMC chambers was to fulfill the VDE 0871.At the end of the eighties VDE founded a special committee discussingthe requirements of alternate test sites. The volume methodfor validating test sites first was integrated in ANSI C 63.4 – 1988.In Cenelec – the European committee – a working group was alsofounded for establishing an EN standard for alternate test sites. Theresult was the EN 50147-1 (shielding) and -2 (NSA site validation).The volume method was integrated in CISPR 16 in the mid nineties.Meanwhile the volume method for NSA measurement of alternate testsites is well established. The technical development of EMC absorberswill be described discussing pyramidal foam absorbers, hollow pyramidalfoam absorbers, and hybrid absorbers – a combination of severalabsorbers (ferrite and foam absorber). New inventions like pyramidalfoil absorbers will also be discussed. The new site validation (siteVSWR) procedure from 1 to 18 GHz is shown.Fifty Years of EMC Research at Georgia TechHugh Denny, Georgia Tech Research InstituteResearch studies in electromagnetic compatibility (EMC) have beenunderway at GTRI since 1953. Investigations have ranged fromstudies of the nonlinear properties of solid state junctions to thedevelopment of control methods for widely dispersed systems.Highlights of accomplishments and contributions during this halfcenturyplus are presented.EMC of Integrated Circuits: A Historical ReviewEtienne Sicard, Institut National des Sciences Appliquées (INSA) of ToulouseThis paper provides a non exhaustive review of the research work conductedin the field of integrated circuit electromagnetic compatibilityover the past 40+ years.Military Aircraft Electromagnetic Compatibility: Release toService Testing in the United Kingdom, Past, Present and FutureTimothy J. Duggan, Systems Evaluation Services, QinetiQRelease to Service (RTS) Electromagnetic Compatibility (EMC) testingof military aircraft in the United Kingdom (UK), can be tracedback as far as 1932 concerning the effect of engine interference on anaircraft’s communication systems. However, it was interference seento aircraft weapons and electrical systems during operations from aircraftcarriers in the 1960s that resulted in the significant expansionof the EMC assessment and test capabilities by QinetiQ (and its predecessororganizations) at Boscombe Down, Farnborough, and by aircraftprime contractors. This paper describes the evolution of EMCtest methods and facilities used to assess UK military aircraft fromthe 1960s to the present and into the future, taking into account theadvances in avionics technology and the associated challenges inassessing their suitability for RTS.EMC MEASUREMENTS IDevelopment and Application of a High-Resolution Thin-Film ProbeKuifeng Hu, University of Missouri-RollaA high-resolution thin film probe was developed and compared to aconventional single loop probe, and showed a 250 µm spatialimprovement measured at a height of 250 µm over 118 µm differentialtraces. A 180 degree hybrid junction was used in the measurementcircuit to separate the electric and magnetic coupling from theprobe. A network analyzer with narrow band filtering was used todetect the weak signal from the probe and further determine thephase. The developed thin-film probe was successfully used to detectthe package pin current with phase information at clock frequencyharmonics.The Design of an Electro-optical Modulator Used in EMCMeasurementsYinan Geng; Rong Zeng; Jinliang He; Shuiming Chen; and Bo Zhang, —Department of Electrical Engineering, Tsinghua University©<strong>2007</strong> IEEE www.emc<strong>2007</strong>.org
