To evaluate the electromagnetic properties of heterogeneous materials using the finite element (FE) method, the appropriate boundary conditions should be defined. The periodic boundary condition is one of the most efficient in terms of convergence ra

In this paper, we present new expressions of the effective constitutive parameters of bi-isotropic multilayered structure having an arbitrary number of layers and different thicknesses. The present method uses the decomposition scheme, and the commut

This paper presents a new approach to impose periodic boundary conditions on arbitrary mesh. This method is based on two steps; the first one consists in writing each unknown of the first side as function of the unknowns of the opposite side. The sec
