Abstract

In this paper the simulation of 3D microwave structures using an FDTD/convolution technique, implemented on a massively parallel machine, is presented. This method allows to reduce the computation and memory requirement in the FDTD simulation by replacing large structures with small modules. Validation of this technique is illustrated by comparing the results obtained for a microstrip structure with the results obtained using a conventional FDTD simulation. The new technique is then used to simulate the passive structure used in quasi-optical 2D amplifiers, with the goal to add the active element later on.
