Organizer:

There are a number of techniques where the impedance of power/ground planes can be analyzed much faster than traditional full wave EM techniques. These techniques include cavity resonance method, boundary integration method, and finite difference method, etc. The purpose of this special session is to compare these solution techniques using a set of pre-defined problem configurations that include simple and progressively more difficult geometries, including capacitors with associated inductance and resistance. Each technique will report the time to solution as well as comparison against known results from full wave tools (or measurements).

The session will include presentations on five different techniques:
