Aperture Coupling to Shielded Transmission Lines: Theory and Experiment

摘要

Coupling through circular apertures in the shields of a coaxial air line and aTEM cell is studied theoretically and experimentally. Polarizability theory is used to compute the effective dipole moments that excite the transmission lines in the internal region. Measurements of shielding effectiveness of both structures were made in a reverberation chamber over wide frequency ranges.
