Backscattering of plane electromagnetic waves of VLF frequency range by thin circular metallic ring antenna with nonlinear load and located into the air nearby the plane boundary between air-dielectric media is investigated. The angle distribution of backscattered field at the double-frequency of sounding signal is studied. The influence of the spherical dielectric core on the backscattered field by the nonlinear loaded antenna is analyzed. Antenna is localized into the isotropic dielectric media. It has been shown that the presence of a dielectric core may lead to an increase of the double-frequency backscattering signal.

Keywords: loop antenna, nonlinear load, scattering of electromagnetic waves, dielectric core, boundary between dielectric media, nonlinear markers.
