چکیده مقاله
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.
