The aim of this paper is to indicate the equations of electromagnetic wave in homogenous and non-homogenous dielectric material, estabilising the bundary conditions and solves by FEM the equations of the electromagnetic wave in the rectangular cavity. By numeric simulation of the waveguide in the cavity there have been studied the modifications of both the ways of propagation and the field’s distribution. The non-homogenous mediums afectes the field’s amplitude, obtaining a non-homogenous distribution. Poyting vector of the wave’s transmision, indicates the energetic flux’s concentration in the air besides the dielectric material.
