Краткое описание

Wave beams with inhomogeneous spatial polarization of the emission are necessary for solving important fundamental and applied problems related to interaction of electromagnetic waves of terahertz range with matter. These include diagnostics of the material surfaces, thin films, biological objects, terahertz systems of data transfer and processing, attainment of sub-wave resolution in the terahertz tomography, terahertz communication systems etc. Results of investigation of specific features of terahertz wave focusing are practically absent. Based on the Rayleigh-Sommerfeld vector theory, a theoretical investigation has been performed of physical features of the moderate and sharp focusing of laser radiation beams excited by modes of the cavity of a circular metal waveguide with different spatial polarization of the field. The obtained results enhance knowledge on the specific features of focusing of terahertz range laser beams.
