Abstract
A method for the FDTD analysis of quasi-optical MESFET arrays is presented in this paper. To analyze active devices such as MESFETs, this method creates a set of field-state central finite difference equations; and all the field and state variables are solved simultaneously at the same FDTD time step. It will be shown in this paper that this formulation is simple and straightforward. The analysis of quasi-optical MESFET oscillator arrays have been performed to show the application of this method. Excellent agreements have been obtained between the results from this simulation method, from commercial softwares, and from experimental measurements to show the validity of this method.
