SCATTERING FROM A BREAK IN THE SHIELD OF A BRAIDED COAXIAL CABLE - THEORY

摘要

An important problem in electromagnetic shielding is to evaluate the influence of a non-uniform braid that forms the outer conductor of a coaxial cable. Using two different analytical methods, the effect of a circumferential break in the shield of a cylindrical coaxial structure is considered. In both approaches, the tangential fields are matched across the gap but different assumptions are made. The final results are given in terms of admittance functions that have a relatively simple interpretation.
