Plasma-covered long cylindrical non-isotropic dielectric lenses for targeted control of energy distribution

摘要: In this paper, a long column lens with circular cross section made of two transversely non-isotropic dielectric parts covered by an isotropic plasma layer, is studied. The response the mentioned object to presence plane monochromatic electromagnetic waves will be investigated. finite element method has been used calculate field equations and amplitudes scattered in research. This structure can purposefully as device focus wave energy specific area that its operation discussed scattering theory. responses have simulated for modes TE, TM incident wave, separately. Since region exists, considered transparent or non-transparent states, variations frequency fixed frequency. Here we consider states too.
