Abstract

This paper is to study coupled microstrip lines on layered yttrium iron garnet/gadolinium gallium garnet (YIG/GGG) structures. The problem is formulated using the spectral-domain technique, and the spectral Galerkin´s method is utilized to compute the dispersion characteristics. Numerical results are presented for various values of structural and physical parameters such as widths of strips, thicknesses of YIG and GGG, separation between the strips, and applied DC magnetic field
