Abstract
A near-field microwave nondestructive diagnostics based on the total reflection phenomenon is described. The new type of schematic solution of device is proposed - a near-field interference microwave sensing system. The test diagnostics results in the conditions of metallized strips with breaks are presented.

Summary
For a long time, unflagging interest has been shown in fundamental research of electromagnetic waves tunneling features. A number of researchers, bearing in mind the formal similarity of the stationary Schrödinger equation and the Helmholtz equation, tried to find the answer based on the classical effects study of electromagnetic waves tunneling through macroscopic photonic barriers [1,2,3] In this case, the air gap d was a uniform photon barrier for radiation beam 1 incident on the small face of prism I, and on the large face at an angle exceeding the angle of total reflection c arcsin(1/ n). The microwaves, generated by Agilent Technologies PNA-L Network Analyzer (N5230C) with the operating band of 10 MHz – 40 GHz are fed into a coaxial conical horn sensor with aperture diameter D =70mm to create a circular Gaussian like beam This beam travels through small side of the prism I, as shown, and immediately penetrates into a symmetrical system, consist of two same prisms.
