Transmission Line Sample HoldersCoaxialWaveguideTransmission line sample holders can be made from coaxial airlines orwaveguide straight sections. Both are widely available in differentfrequencies from Agilent and other connector manufacturers. Samples mustfit inside. This technique works best for hard solids that can be machined. Itis possible, although more difficult, to contain liquids and powders insidethese. Coax sample holders offer broadband frequency coverage, but it ismore difficult to machine solid materials to the shape needed to fit inside.Waveguide straight sections offer banded frequency coverage, but it is mucheasier to machine solid materials to fit inside.35
