Abstract :
An analytical spectral model to efficiently characterize direct power detectors located on the focal plane of focusing THz systems is presented. The model is obtained by extending a Fourier Optics like representation of the electromagnetic field in the focal plane to the THz domain and combining it with a recently developed equivalent network representation. This analytical model is then use to efficiently design the whole system (focusing system and detector).
