RADIO PHYSICS AND RADIO ASTRONOMY

Subject and Purpose. The study of the effect of reflectionless electromagnetic waves propagation through solid-state structures containing metasurfaces at its boundaries has a great scientific and practical interest for improving the performance and creating
new types of nanoelectronics and optics devices. The aim of this work is to study the effect of an anisotropic uniaxial plasmon metasurface located at the boundary of the dielectric layer on the eff ect of reflectionless propagation of electromagnetic waves. The study of the effect of reflectionless propagation of electromagnetic waves through solid-state structures containing metasurfaces at its boundaries is of great scientific and practical interest for improving the performance and creating new types of nanoelectronics and optics devices.

Methods and Methodology. Numerical simulations were used to study the effect of the reflectionless electromagnetic waves propagation through an anisotropic uniaxial plasma metasurface lying on the dielectric layer. It is used to determine the thicknesses and permeability values of the dielectric layer, for which the effect was observed.

Results. It is shown that the presence of an anisotropic uniaxial plasmon metasurface on the dielectric layer leads to a significant conditions change of the effect of reflectionless propagation of p-polarized electromagnetic waves along and across the main axis of anisotropy of the metasurface. It was shown that the metasurface removes the rigid restriction of the dielectric layer permeability value. To achieve the effect of reflectionless propagation of electromagnetic waves, the permeability of the dielectric layer can be chosen within a wide range.

Conclusion. Dielectric layers with anisotropic uniaxial plasmonic metasurfaces have significantly better characteristics for the effect of reflectionless propagation of electromagnetic waves. Th ey can be used to create fundamentally new nanoelectronic and optical devices.

Keywords: p-polarized electromagnetic waves, reflectionless propagation, uniaxial plasmonic metasurface, reflection coefficient
