Analytical study of microwave structures printed on anisotropic substrates based on the Wiener-Hopf technique

An analytical approach for the study of microwave devices and antennas printed on anisotropic substrates is presented. This is based on the geometrical optics approach in conjunction with a reflection coefficient established through a Wiener-Hopf solution of the corresponding canonical problem. A parallel plane waveguide with a semi-infinite upper conductor and loaded with a plasma magnetized parallel to the edge of the truncated plane conductor is considered. The scattering problem of the dominant extra-ordinary TEM wave normally incident up on the edge of the truncated conductor is formulated in the Fourier transformed domain and solved using a Wiener-Hopf technique.
