An Approximation of Pattern Analysis for Distorted Reflector Antennas Using Structural-Electromagnetic Coupling Model

Based on the concept of structural-electromagnetic field coupling, an approximation method is developed to analyze the radiation pattern for distorted reflectors. In this method, the integration point deformation is obtained by a local interpolation scheme which utilizes the same shape functions as...
