Abstract
A number of possible applications of wire metastructures (WM) are revised and presented in the paper. It is shown the structure that consists of parallel metallic wires can provide broadband transmission of electromagnetic (EM) signals over a distance. Based on this, an endoscope of the microwave and terahertz frequency bands was proposed, which able to function at values of the bending radius of the structure corresponding to less than wavelength. One can find that the bending of the structure does not affect the losses' dispersion function. The different type of WM is the irregular WM that can be applied to broadband antennas design. In this case the effect of broadband radiation is achieved, in contrast of usage of a WM with parallel wires arrangement, where radiation can be achieved only at frequencies of Fabry-Perot resonances.
