TLDR
In this paper, a PISCES-like semiconductor model can be joined non-invasively to finite difference time domain models for the calculation of coupled external electromagnetics.Abstract:
We show how PISCES-like semiconductor models can be joined non-invasively to finite difference time domain models for the calculation of coupled external electromagnetics. The method involves "tricking" the standard current boundary condition for the device model into accepting an effective parallel external capacitance. For nearly steady state device conditions we show the results for a transmission line-coupled PISCES diode agree well with those for an ideal diode. >read more

Integrated FDTD and solid-state device simulation
TL;DR: A mixed-mode circuit simulation technique is presented, based on the lumped-element finite-difference time-domain (FDTD) scheme, which makes the formulation and characterization of analytical, closed-form models for circuit devices unnecessary and allows for directly correlating device behavior and fabrication process parameters.

Numerical solution of initial boundary value problems involving maxwell's equations in isotropic media
Abstract: Maxwell's equations are replaced by a set of finite difference equations. It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is given of the scattering of an electromagnetic pulse by a perfectly conducting cylinder.
