A method to simulate an open boundary problem within the Finite Differences Time Domain (FDTD) approach for the emission of photo-conductive antennas is presented here. For this purpose we use convolutional perfectly matched layers (CPML). In these devices, the semiconductor region, where transient currents are present in simulation time, is considered to be an "active" medium. This medium is extended virtually beyond its boundaries or the computational domain limits. We explain in this paper
