Abstract
Mathematical simulation of nonlinear effects of frequency multiplication in a semiconductor microstructure with negative differential conductivity (SMNDC) and parametric amplification in an SMNDC with a traveling domain in a microwave strip cavity has been performed based on the solution of a nonlinear 3D diffraction problem. The conditions of occurrence of self-oscillations in the SMNDC depending on the bifurcation parameters (bias field strength and electron concentration in the SMNDC) have been analyzed proceeding from bifurcation points of the nonlinear Maxwell operator.
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
