FINDING THE ELECTROMAGNETIC HOMOGENOUS EQUIVALENT OF THE COMPOSITE MATERIAL USING GLOBAL OPTIMIZATION TECHNIQUES TO SOLVE THE INVERSE PROBLEM

Jana Jilková

Abstract

The equivalent homogeneous isotropic replacement is computationally efficient way how to enable simulation of the large numeric models of the composite aircrafts for the purpose of precertification electromagnetic compatibility tests to estimate the level of their resistance against the lightning. The paper presents application of two global optimization methods to find an appropriate electromagnetic equivalent of the composite material by homogeneous material to reduce CPU demands of the numeric models of elec¬trically large airplanes for the purpose of electromagnetic compatibility simulations. First, the inverse problem is specified using the already known scattering parameters of the composite material. Afterwards, the global optimization method is applied to find the equivalent with such a value of the complex electromagnetic permittivity to have the impact on the electromagnetic field propagation as close as possible to the original composite material.
