Abstract
Excitation of THz surface plasmons due to the scattering of transverse magnetic (TM) wave by an elliptical plasma antenna consisting of a metallic rod with dielectric coating is investigated. The incident, transmitted, and scattered electromagnetic waves are expressed in terms of Mathieu and modified Mathieu functions. The geometrical structure and its effect on the scattering crosssection and resulting resonance frequencies are studied and analyzed based on theory of Fabry-Perot resonator. It is shown that the resonance frequency can be varied by changing the geometrical structure and material used between the surfaces of this structure.
