Description
Summary:A discrete method or concept, which makes use of the spherical dyadic Green's functions (DGFs), is developed to study the electromagnetic transmission through an axis-symmetric radome of superspheroidal shapes. By means of the dyadic Green's functions, the discrete method inherently accounts for the curvature effects of the radome shell, which is generally ignored in classical approaches such as the ray-tracing method and the plane wave spectrum analysis. This proposed discrete method is thus able to give a more accurate analysis on the electromagnetic transmission problem through an airborne radome of superspheroidal shapes. Numerical results on power patterns and boresight errors are obtained and compared for various geometrical parameters of a superspheroidal radome.
