In this work, we consider the possibility of enhancing terahertz bolometric detection efficiency using resonant structures in the case of an inclined incidence of radiation. The structures are made of a sequence of doped and undoped semiconductors, including epsilon-near-zero areas. Undoped regions act as electromagnetic resonators, thus ensuring resonant signal penetration through the opaque (doped) regions of the structure. A set of epsilon-near-zero areas can ensure substantial enhancements to the electric field in the material. In the doped regions, absorption occurs. The structure described above can provide efficient resonant energy absorption for a wide range of angles of incidence. The numerical calculations based on the solution of the Helmholtz equation have shown that the studied resonant structures ensure the absorption of up to 50% of the incident radiation energy for a 60-degree incidence.

“…On the other hand, we have demonstrated the ability to replace the 'capricious' ionized gas with a convenient semiconductor plasma in experimental tests and practical devices [31][32][33][34]. The successful demonstration of resonant signal transmission through the semiconductor plasma with supercritical density gives rise to our future experimental study of GHz signal tunnelling through the air plasma in the conditions close to those during a real vehicle reentry.…”

We present an experimental study of the effect of resonant tunnelling of radio frequency signals through a silicon semiconductor plasma sheet with supercritical electron density. The resonance effect appears when a dielectric plate is placed behind the plasma sheet and is determined by the dielectric parameters. The numerical modelling of the effect under the experimental conditions was implemented and compared with the experimental data. The features of the wave resonant tunnelling effect in the case of a high-collisional semiconductor plasma were analyzed. This study confirms the proposed earlier method of overcoming the radiocommunication blackout problem.

“…In our previous article [ 41 ], we considered utilizing well-known resonance effects [ 42 , 43 , 44 , 45 , 46 , 47 ] to increase the efficiency of any bolometric detector. By choosing the material and thickness of the dielectric substrate that acts as a resonator so that a half-integer number of standing wavelengths can fit within this size, we can significantly increase the probability of detecting individual photons.…”

It is known that the dielectric layer (resonator) located behind the conducting plate of the bolometer system can significantly increase its sensitivity near the resonance frequencies. In this paper, the possibility of receiving broadband electromagnetic signals in a multilayer bolometric meta-material made of alternating conducting (e.g., silicon semiconductor) and dielectric layers is demonstrated both experimentally and numerically. It is shown that such a multilayer structure acts as a lattice of resonators and can significantly increase the width of the frequency band of efficient electromagnetic energy absorption. The parameters of the dielectric and semiconductor layers determine the frequency bands. Numerical modeling of the effect has been carried out under the conditions of our experiment. The numerical results show acceptable qualitative agreement with the experimental data. This study develops the previously proposed technique of resonant absorption of electromagnetic signals in bolometric structures.
