Abstract :
A new method is proposed to derive the dyadic Green´s function for stratified dielectric layers from the wave equation in spectral domain. The result is a clear equivalent circuit of the whole structure which combines the TE and TM modes by hybrid block matrices. It is simple to apply and evaluate. The relation to the conventional immittance approach is shown by means of a similarity transform which diagonalizes the submatrices. The simplicity of the method is demonstrated in the application to the well-known example of a single microstrip patch on a grounded dielectric layer as well as structures with multiple layers and metallizations in arbitrary interfaces
