RÉSUMÉ

One of the main problems arising in the implementation of the terahertz band is associated with the need to provide the advanced equipment developed in this frequency band with effective electronic components. This paper provides a comparative analysis of the characteristics of the terahertz band components, based on the solid-state elements and waveguide electrodynamic structures. The features of design solutions in the process of creating semiconductor components and devices, such as oscillators, amplifiers, frequency multipliers, power meters, transmission lines, and devices for modulating electromagnetic waves using p–i–n-structures, are shown. The main directions of practical application of apparatus and equipment of the terahertz band are considered. The attractiveness of the terahertz band to create high-speed communication systems, high-resolution radar, radio vision systems, remote identification devices of substances, and other special and civil engineering, is shown. The provided data indicate the potential capabilities of leading Ukrainian enterprises in solving the problems of exploring the terahertz frequency range.
