Nalysis of wave focusing by axisymmetric magneto-dielectric Maxwell and Mikaelian lenses using a modified hybrid projection method

A problem of electromagnetic wave scattering on axisymmetric inhomogeneous magneto-dielectric objects is considered. A modified algorithm based on the hybrid projection method is developed for providing an option of taking into account not only variable profile of dielectric permittivity of the object as it took place in the previous publications, but also variable profile of magnetic permeability. The new modification is applied for comparative analysis of plane wave focusing by a hemispherical Maxwell lens and a cylindrical Mikaelian lens with axial symmetry. The results obtained with use of the hybrid projection method are compared to the results obtained by the method of surface integral equations applied to layered models of the lenses. Some results demonstrating the influence of matching the lens surfaces to free space by means of using identical profiles of permittivity and permeability on the quality of focusing are presented and discussed.
