We have successfully built a multi-mode approach, and also developed several numerical models to approbation of the results obtained. This approach was successfully applied to the study of coupled systems of different geometries and boundary conditions. The interaction of different types of metasurfaces with the reinforcing medium was studied. A systematic and accurate analysis of the dynamics of passive and active assemblies of nanoparticles was performed with the practical goal of building a light generation device (a fully dielectric SPASER analogue). A remote method of controlled plasma heating is also proposed, which is based on the use of the phenomenon of the Exceptional point of a connected system of dielectric and plasma waveguides. Loss compensation in the gyrotron resonator was studied. Using a self-consistent approach, it was shown that errors in the processing of a complex resonator led to an increase in the starting current of the operating mode. The possibility of multi-mode operation of the gyrotron due to corrugation of the resonator surface with the specified parameters has also been proven.
