Here we propose a generalized physical approach providing possible technical realizations of a number of urgent problems related to the interaction of electromagnetic radiation with plasma and conducting media. Proposed approach is based on the use of well-known optical-mechanical analogy which exploit mathematical identity of the stationary Schroedinger equation in quantum mechanics for the particle motion in potential field and Helmholtz equation in wave theory. We present an analysis of the possibility of penetrating electromagnetic waves through opaque media using the analogy of tunneling of a quantum-particle flux through a potential barrier. As an example, we consider plasma sheath surrounding the vehicle as a potential barrier and analyze the overcoming of radiocommunication blackout problem. The idea is to embed a «resonator» between the surface on the vehicle and plasma sheath which is supposed to provide an effective tunnelling of the signal to the receiving antenna. We discuss the peculiarities of optical mechanical analogy applicability and analyze the radio frequency wave tunneling regime in detail. The cases of normal and oblique incidence of radiofrequency waves on the vehicle surface are studied [1]. One more promising application of the suggested approach implies a method for increasing the efficiency of bolometric photodetectors. The results of calculations show that by choosing thickness and dielectric constant of the substrate-resonator under a thin layer of metal (superconductor) one could brought the fraction of absorbed radiation in the detector to a value close to unity at a certain frequency of the infrared range [2]. 1) Bogatskaya A.
