A Volume Current Based Method of Moments Analysis of Shielded Planar 3-D Circuits in Layered Media

Method of moments analysis of planar multi-layer circuits typically assumes conductors are infinitely thin and only surface currents need be modeled. Modern fabrication techniques, especially for high frequency integrated circuits, can easily create structures that require modeling volume current. Combined with previous work, this paper presents, for the first time, a complete volume current based method of moments analysis of shielded multi-layer circuits.
