Measurements of a Harmonic Generation Factor of Radio Absorbing Materials in the Microwave Range

It is proposed to use a model of the coaxial measuring cell for estimating an intensity level of harmonics of a radio absorbing material (RAM) in the microwave range. Measurement results of the harmonic factor of a film RAM are given. It is shown that the harmonic factor substantially increases, as the power level of the sounding frequency rises, and its dependence on the length of the studied samples is also shown.
