pp: 522-525Coupling of Microstrip Lines Exciting the Magnetostatic Surface WavesJaehyun Lee doi:10.2529/PIERS061007062850 Downloads: 945 Abstract:The coupling of microstrip lines which excite the magnetostatic surface waves is analyzed. The asymmetric excitation of microstrip line and the nonreciprocal propagation characteristic of the magnetostatic surface waves are considered. For the fast numerical calculation, the Jacobi polynomial is used as the basis function to satisfy the edge condition.References:1. Ganguly, A. K., D. C. Webb, and C.
