Abstract-A novel computational method based on full-wave analysis of stripline planar structures with vertical interconnects in multilayer dielectric media is presented. The method is based on the electric-field integral-equation solved with the Method of Moments (MoM). The special characteristics of stripline structures facilitate the extensive use of semi-analytical techniques to analyze the multilayer structures, limiting significantly the use of purely numerical techniques. The accuracy of the proposed modeling method is examined thoroughly with extensive numerical tests and the results are compared with results generated by commercial simulators for simple stripline structures.
