3D time-domain electromagnetic/transport macroscopic numerical physical modelling

Abstract

A new 3D time-domain physical numerical electromagnetic/transport modeling has been used to investigate the photoswitch (PS) operation. It is mainly based on a self-consistent solution of both the Maxwell and drift-diffusion equations by means of the FDTD method. The model has been applied to a GaAs microstrip line photoswitch. Some results illustrate the model capabilities. Some circuit functional quantities are determined as a function of RF operation parameters. Some features of the PS transient operation as a function of the semiconductor material transport parameters are described.
