Abstract :
This contribution deals with the analysis of the Transmission-Line Holder measurement system for determination of shielding effectiveness for material samples. Two different material sample configurations will be analysed, material sample with conductive and non conductive surface. In this part, the TLH with capacitive and galvanic coupling will be analysed. This TLH is called TEM-2000. Analysis will be based on electrical circuit diagrams, calculation of transfer functions and Z-Parameters with analytical determined electrical parameters. Finally, a comparison of the analytical solution with a shielding effectiveness measurement will be done.
