Abstract: A new test method is presented to determine the stress and strain within the syn-thetic material parts using super high frequency electromagnetic wave of the polarization to transmit it. The relationship between the stress, strain and dielectric constant, the structure and working principle of the test instrument, and the practical examples are given.
