Analysis of finite-micro strip structures using surface equivalence principle and multiple network theory (SEMN)
MetadataShow full item record
Two techniques based on electric and magnetic field integral equation (EFIE and MFIE) formulations of surface equilalent principle and multiple network theory (SEMN) method are developed for the analysis of finite microstrip structures. Using pulse surface basis functions, the surface of each homogeneous dielectric body is modeled by small flat segments of arbitrary geometry and constant electromagnetic field. Using the surface equivalence principle and the Green's functions of the homogeneous space, the admittance and impedance matrices are computed. Then, the boundary conditions and multiple network theory are applied to determine the overall characteristic of the entire space. Several radiation and scattering examples are numerically analyzed and their calculated near and far fields are presented. The numerical results of the two formulations are then compared with measurement and those of HFSS and ENSEMBLE.
