摘要

In this study, the problem of electromagnetic scattering by and radiation from arbitrary conducting and dielectric coated wire, surface, and junction configurations are investigated. The electric field integral equation (EFIE) is formulated in the frequency domain using the vector and scalar potential description for an arbitrarily shaped, perfectly conducting structure consisting of an arbitrary number of surfaces and wires. The surfaces are modeled by planar triangular patches. The thin wires are modeled by piecewise linear segments. The wire radii may vary discontinuously. A special basis function is introduced at each of the wire/surface junctions. A simple and efficient modeling technique is applied to account for the presence of the thin dielectric materials. The integral equations are formulated using the equivalence principle. The method of moments is then applied to solve for the currents induced on the boundary surface of the system. An important feature of the algorithm developed is its ability to handle wire-to-wire, surface-to-surface, and wire-to-surface junctions. Examples of such applications include vehicular antennas and wire antennas for shipboard, airplane, and satellite communications.
