Abstract
Methods for the calculation of the propagation coefficient of a rectangular waveguide containing a centrally placed semiconducting film are discussed. Numerical solutions for such a system with film resistivities in the range 10Ω–10kΩ/square and frequencies in the range 8.4–12GHz have been made, and confirmed experimentally at 9.25GHz. The theoretical results indicate the possibility of constructing waveguide flap attenuators with high attenuations and very small phase shifts.Keywords
