Abstract :
A general approach for including lumped circuit elements in a finite difference time domain (FDTD) solution of Maxwell´s equations is presented. The methodology allows the direct access to SPICE to model the lumped circuits, while the full 3-dimensional solution to Maxwell´s equations provides the crosstalk and dispersive properties of the microstrips and striplines in the circuit.<>
