Experimental Study of a Metal Cylinder with Nonlinear Loads which Covered with Metamaterial

In this paper, the experimental study of a metal cylinder with nonlinear loads which covered with metamaterial, is conducted. Previous works showed the possibility of aligning levels of the field scattered from the metal cylinder with nonlinear loads, which is covered with metamaterial, due to the appearing of the nonlinear scattering effect. Frequency characteristics of the scattered field for an experimental model of a metal cylinder loaded with nonlinear structure, which covered with MM, are experimentally received for different radii of cylinder. It's shown that for investigated "nonlinear" cylinder for some cases the level of the second harmonic may be only on 8 dB lower than the level of the scattered field at the fundamental frequency.
