Numerical modeling of the ELECTROMAGNETIC WAVES interaction with microporous structure absorber

Abstract

Сonsistent physics and mathematics model of electromagnetic waves propagation in heterogeneous medium using the generalized wave equation and the Dirichlet theorem is built. The data of numerical simulation of the electromagnetic interference interaction with a fibrous material having a double porosity. The results of numerical simulation show that the presence of micro- and macropores (medium with double porosity) of the fabric ensures maximum masking effect.
