The Analysis of the Two-Wire Transmission Line in a Cavity with Apertures Illuminated by a Plane Wave Based on Electromagnetic Topology
By using electromagnetic topology (EMT) method, this paper discusses the issue of the electromagnetic field penetration through an aperture to a cavity and coupling to a two-wire transmission line in the cavity. By representing the electromagnetic field propagation path as “tube”, and combining with transmission line theory, this paper creates the Baum-Liu-Tesche (BLT) equation of radiation coupling. Then, by employing the BLT equation, the semi-analytic solutions of the load response of the two-wire transmission line in the cavity are obtained. Numerical examples are constructed to demonstrate the validity of this technique.
