The article contains a systematized account of experimental and theoretical aspects of the nonlinear effect of the generation of harmonics and combination frequencies at metal-oxide-metal contacts at radio frequencies. The special features and the regularities of nonlinear scattering of radio waves by metallic objects containing these types of contacts are investigated.
