    It is now possible to use optoelectronic techniques to both generate and measure electrical waveforms with subpicosecond rise times. These rise times invalidate assumptions commonly made in developing equivalent circuit models for transmission lines and other simplifications commonly made in modeling conductivity. In this paper we discuss how a combination of direct finite-difference time-domain solutions of Maxwell’s equations and Monte Carlo models of photocarrier transport can be used to avoid making these assumptions.
