The approach within the overlapping partial domain method has been considered in this paper. Proposed approach allows solving diffraction problems in which a system of integral equations for unknown partial domain functions cannot be reduced to a single integral equation for one unknown function. The electromagnetic wave diffraction problems on an infinite phased array antenna and on a cascaded junction of rectangular waveguides are considered.

Mathematical model and simulation results of devices with intervalley electron transfer effect based on graded-gap semiconductors are presented in this article. Drift of space-charge waves and the occurrence of self-oscillations in such devices are analyzed. Moreover, this paper aims to show that the use of graded-gap semiconductors makes it possible to obtain the generation in the sub-terahertz range.
