Etude quasi-TEM de structures planaires avec subtrat composite vdiélectrique ferrite par la méthode des moindres carrées

Abstract

In this work, the modified least squares boundary residual method LSBRM is utilized,which takes into account electromagnetic field singularities at the metal -dielectric edge with the use of systematic weighting functions which accelerated the convergence. The study is presented for different planar structures: the shielded micro strip line for which we have calculated the line parameters (the propagation constant, the characteristic impedance and the phase shift ). Our results are in a good agreement with those published in the literature. Indexing terms: least squares boundary residual method, modified least squares boundary residual method, electromagnetic field singularities, shielded micro strip line .
