Dielectric radome analysis using adaptive integral method

Abstract

An adaptive integral method (AIM) solution is described for the problem of electromagnetic transmission through radomes of arbitrary shape. The far field transmitted through a radome excited by a dipole array is studied. The computed results for spherical radome are in excellent agreement with the exact results. The application of AIM significantly reduces the memory and CPU time requirement for solving the integral equation. Hence, the algorithm presented in this paper can be applied to efficiently and accurately analyze dielectric radomes of sizes much larger than those that can be analyzed by a direct numerical method.
