Abstract

The purpose of this paper is to present a method of material design of functionally graded material (FGM) plates with a function of electromagnetic noise suppression under an incidence of electromagnetic plane wave. The FGM plates are considered as multilayered plates while electromagnetic properties are homogeneous inside the same layer. The approximate analytical solutions of electromagnetic field in the multilayered plates are therefore derived for electromagnetic plane waves. The expressions for reflection and transmission coefficients are then obtained based on the above analytical solutions. In this paper epoxy resin/titanium oxide FGM plates for numerical calculations were used with a graded composition expressed in the form of power function. The effects of the graded composition and thickness on the reflection and transmission coefficients were then quantitatively evaluated, and the suppression effect of electromagnetic noise was discussed.
