Homogenization of Sub-Wavelength Inhomogeneities for Analysis and Design of Terahertz Spoof Plasmonic Structures, Ph.D. Dissertation Sharif University of Technology ; Mehrany, Khashayar (Supervisor)
Abstract
In this thesis we investigate the use of periodic array of metallic structures which mimics the propagation of the surface plasmon-polaritons waves. The TEM modes supported by these structured surfaces are referred to as the spoof surface plasmon-polaritons. They have many properties in common with the electron plasma and can be described by a plasma-like effective permittivity, when the structure is on a scale much smaller than the wavelength. In this thesis we extend this concept to include different kinds of structured surfaces like cut through metallic slits array and square array of rectangular metallic pillars which support TEM modes. We show that although these structured surfaces...
