Implementation of surface impedance boundary condition in FDTD and Incorporating EMI from traces crossing the gaps in the ground plane into SPICE

Abstract

"This thesis consists of two sections. In Section 1, an efficient implementation of a surface impedance boundary condition in the Finite Difference Time Domain method is introduced. This algorithm is implemented in FDTD to include skin effect loss due to the finite conductivity of good conductors. Two test cases are simulated to show the effect of skin effect loss in good conductors.

In Section 2, a full-wave FDTD model for the estimation of EMI due to the gaps in the ground plane is compared with a SPICE model. It is also shown that circuit simulators like SPICE are much faster than the full-wave FDTD method and can predict signal quantities fairly accurately”"--Abstract, page iii.
