Abstract

A simple moment solution is given for the problem of the electromagnetic transmission through two-dimensional radomes of arbitrary cross section. The radome is composed of one or more layers of lossy dielectric shells of arbitrary cross sections. The reflectors consists of conducting strips next to the outer surface of the radome. The equivalence principle is used to replace the surfaces of the radome and the strips by equivalent electric and magnetic currents. The boundary conditions on the tangential component of the total electric field yields a set of coupled integral equations for the eequivalent currents. The integral equations are solved by the method of moments with pulse expansion and point-matching technique. The effects of the surface-wave excitation and the interaction among the various portions of the dielectrics and the reflecting strips are automatically included in this solution. Computed results are the equivalent surface currents, the near field and the far field. The computed results are in very good agreement with whatever published data available.
