Some characteristics of radiation field of rotating charged particle about a dielectric metamaterial sphere

Electromagnetic fields of a relativistic charged particle rotating about a dielectric sphere of double- negative and epsilon-negative metamaterial is investigated. Some features of radiation is compared by conventional medium. It is shown that in the case of transparent medium the transmitted field mostly concentrate near surface for conventional and double negative medium but it is divergent for epsilon –negative material.
