Activity: Talk or presentationTalk or presentation at a conference


A revised version of the Norton equivalent circuit proposed in [1] is presented in order to describe more accurately the saturation at high optical powers. The revised model relies on an improved characterization of the generator impedance, now approximately one order of magnitude lower then the previous one and comparable to the impedance of the bow-tie antenna. The model is validated with a full wave simulation of the photoconductive antenna (PCA) in CST MWS. The proposed simulations are discussed in details and are presented as a new tool in literature to model PCAs.
