ELECTRODYNAMIC MODEL OF A DIFFRACTION OF AN ELECTROMAGNETIC WAVE FROM A SOURCE WITH AXIAL SYMMETRY ON AN ECCENTRIC MAGNETODIELECTRIC SPHERE
On the basis of the analysis of distribution of densities containing reserved energy in a nearby zone of electrically small radiators covered with impedance covers from magnetodielectric metamaterials, opportunities and urgency of a task of reduction of the distance between radiators of an antenna lattice for creation of the small-sized superdirected antenna system are shown. The solution of an external task - diffraction of an electromagnetic wave radiated by the Hertz dipole, surrounded by a magnetodielectric spherical cover, on an eccentric magnetodielectric sphere is given. The ratio allowing to calculate external and internal fields, diffracted by a magnetodielectric covering enveloping the passive antenna are received.
