TM SCATTERING AND TRANSMISSION PROPERTIES OF AN ARBITRARY SLIT IN A CONDUCTING PLATE
导电平板上任意孔缝的TM波散射及传输特性分析

This paper deals with the electromagnetic characterization of the transmission and scattering properties of a slit in a conducting plate for TM polarization. To alleviate compu-tational constraints for the problem, a connection algorithm is developed based on mjcrowave network theory. In this paper, the slit can be divided into sections and the generalized admittance matrix of each section can be computed by the boundary integral method. Using the connection algorithm, the aperture admittance matrix of the slit can be derived by cascading the admittance matrices of individual sections. Once the slit aperture admittance matrix is ob-tained, equivalent magnetic currents, the backscattered neld, and the transmission coefficient are found by the generalized network principle.
