I. Makarov P.A., Ulyasheva M.A On the theory of dispersion of gyromagnetic waves in a medium with dissipation
Gyromagnetic waves propagating in a tangentially magnetized ferriteslab with bi-gyrotropic properties was considered. Dissipation of themagnetic permeability of the material was considered. In the DamonEshbach geometry a system of transcendental equations was obtained. Thissystem determines the dispersion of the wave vector components.
Keywords: gyromagnetic waves dispersion, dissipation.

Game engine core, written in C++, was released as a result of work. Currently, working with this core is quite difficult because of language specific. Further development of tools for reducing difficulty is planned. In next versions realization of tools for previewing of page layoputs also is planned. Also in future changing Skia with custom rendering core with tessalator for vector graphics is planned< due to needs of optimizations of concrete projects.
