Abstract

Nowaday, it becomes necessary to characterize materials on a very large bandwidth for frequencies up to 100 GHz. Photoconducting microdipole antenna benches have already shown their ability to answer such a problem. Before the realization of such benches, a theoretical design of the antennas is necessary for the prediction of their behavior (transient radiated free field duration, frequency bandwidth. . .). For this reason, we propose in this paper, a theoretical approach based on the coupling of different tools: the finite difference time domain method (FDTD), a drift diffusion model for considering photoconducting materials and the geometrical optic for the lens modeling. After the description of the software, some results will give the capabilities of such an approach.
