Parallel plate waveguide simulator design, characterisation and DUT de-embedding

In this paper, a new hybrid measurement/3D EM simulation technique to obtain reflection and transmission properties of an FSS under normal incidence has been investigated. The measurement fixture, a specially designed PPW simulator operating with normal incidence excitation, can be very accurately computed by commercial 3D EM simulation. To reveal the de-embedded characteristics of the DUT, (in this paper a wire FSS), a de-embedding method employing half structure models has been performed. This results in good agreement with theoretical prediction.
