Abstract
A new technique is suggested to measure phase shifts of electromagnetic waves transmitted through a 1D wire grating in the case of normal incidence. To implement the proposed technique an HCN-laser was involved which instruments are widely used in the capacity of THz-range sources of radiation. The output mirror of the laser was represented by the grating to be investigated and a solid mirror with an aperture. Physically the technique is based on determining the difference length of the laser resonator in the course of lasing in turn at two polarizations with the polarization vector being oriented in parallel and perpendicular to the grating wires.
KEY WORDS: one-dimensional wire grating, phase shift, polarization, laser radiation, HCN-laser
