Non-ideal multifrequency cloaking using strongly dispersive materials
چکیده انگلیسی
Non-ideal multifrequency cloaking of dielectric cylinders is expected to be realizable by using single-layer coating shells, which are made of isotropic homogeneous dispersive materials. In the present paper, scattering on the coated cylinders is studied for the Drude-Lorentz materials with frequency dependent permittivity and permeability. The exploited physical mechanism is based on the Fabry-Perot-type radial resonances arising in the coating shells. The obtained simulation results confirm the possibility of a strong reduction of the total scattering cross section at several frequencies simultaneously. Resonance frequencies can be estimated by using simple algebraic equations. The suggested mechanism can be used for TE and TM polarizations within a wide range of the variation of the diameter-to-wavelength ratio.
