Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description2 The work on the project was performed in line to the requirements of the Terms of Reference for 2021. The research method is the modeling of the electromagnetic fields in the presence of the nanostructures for the micro and nanolaser cjnfigurations, built on active circular quantum wires with graphene shells, graphene strips on the surface or inside such quantum wires, graphene strip gratings on the flat active quantum substrates, and graphene disk on the surface of the active disk, combining Maxwell’s boundary-value problems with quantum-theory description of graphene. The boundary value problems are reduced to infinite matrix equations or their systems, which allow to obtain numerical solutions with guaranteed accuracy. Testing of the corresponding computer programs has been carried out by means of the verification of satisfaction of the general relations, such as the power conservation law, the boundary conditions on the nanostructure elements, and also by the check of convergence of the obtained results. In some cases, these results are compared with known data obtained by approximate methods. High-speed computer programs for the numerical solution of the wave scattering and eigenvalue problems for the studied nanolaser configurations have been developed. To verify and optimize the proposed methods and computer codes based on them, systematic numerical experiments on the scattering of waves of a given frequency by these nanostructures were performed. The considered problems of wave scattering demonstrate resonance effects, the frequencies of which correspond to the frequencies of the eigenmodes and can serve as convenient initial approximations in the numerical study of nanolaser modes. As these results have independent value in the wave nano-optics, 7 research papers have been published in 2021 in the leading international journals on optics and photonics.
