Full Wave Matching Circuit Optimization In XFdtd

Determining the final set of component values in a matching network can be a challenging process. Traditionally, RF engineers have had to simplify and idealize their matching circuits in schematics that are separated from the EM simulation. This simplification into a lumped element schematic requires perfect grounds and leaves out the coupling and transmission line effects of the interconnect metal and the antennas.
