Iterative Perturbation Theory for Methods of Moments Applied in Impedance Coated Dielectric Radomes

摘要

Perturbation theory, if applicable, can provide significant acceleration for parameter optimization. In this work, perturbation theory is developed in scattering problems under the framework of methods of moments. Perturbative expansion series are obtained which are convenient to calculate by an iterative algorithm. The series are tested for surface impedance coated dielectric radomes. This theory is especially useful for derivative-dependent optimization methods.
