Analysis of Space and Surface Waves Excitation in Layered Magnetodielectric and Metamaterial Structures in the Context of Radiation and Diffraction Problems

The Green´s functions of grounded magnetodielectric slabs with LE, LM waves´ expansion and layered circular cylinder with E, H waves´ expansion are used for surface and space waves analysis. Traditional magnetodielectrics and double negative materials are under consideration. Radiation patterns of surface waves excited by a slot covered with double-positive and double-negative permittivity and permeability media are obtained. A scattering from covered cylinder are considered. Angularities of back scattering coefficient are connected with azimuth electrical current resonances.
