“…For chiral cylinders, these properties result in a coupling of the TM and TE polarizations. Analytic solutions describing elliptical cylinders with chiral media are given by [15][16][17][18]. The analysis and the software used for obtaining the results have been validated, by calculating the normalized backscattering widths for semi elliptical conducting cylinder, and showing that these results are in excellent agreement .…”

An exact solution is presented to the problem of scattering of a plane wave by a chiral semi-elliptic-cylindrical boss located on an infinite perfectly conducting ground plane. The problem is formulated by expressing the incident, reflected, scattered as well as the transmitted electromagnetic fields in terms of appropriate angular and radial Mathieu functions and sets of expansion coefficients. The unknown expansion coefficients can be determined by imposing the appropriate boundary conditions on the surface of the chiral semi elliptical cylinder. Numerical results are presented for radar cross section of semi-elliptic-cylindrical bosses of different chiral material, to show the effects of these on it.

“…Numerous authors have investigated the radiation properties by dielectric coated slotted circular and elliptical cylinders [1][2][3][4][5][6][7]. Materials possessing both lossy and lossless metamaterials as well as chiral material have gained considerable attention by several researches [8][9][10], while possessing anisotropic and anisotropic plasma materials have been studied by [11][12][13][14].…”

Radiation properties of axially slotted elliptical antenna embedded in anisotropic plasma material are studied theoretically. The fields are expressed in terms of Fourier series with unknown constants. The radiated field constants are obtained using the boundary value method by invoking the boundary conditions at various surfaces. Results are plotted graphically for the radiation patterns for different geometries and electrical parameters. The results show that the presence of the anisotropic plasma coating has affected the main beam while elliptic antenna beam is less oscillated compared to circular one for the same coating thickness

The radiation properties of an axially slotted elliptic antenna coated with magnetic metamaterials are investigated. The fields inside and outside the dielectric coating are expressed in terms of the Mathieu functions. The boundary conditions at various surfaces are enforced using the orthogonality property of angular Mathieu functions. Numerical results are presented graphically for the radiation pattern, aperture conductance, and antenna gain for the TM case. It was found that a slotted antenna coated with magnetic metamaterials has more gain as well as lower side lobes compared to one coated with conventional dielectric or nonmagnetic metamaterials.
