摘要

摘要在解决非线性三维衍射问题的基础上，对具有负差分电导率的半导体微结构（SMNDC）中的频率倍增非线性效应和微波带状腔中具有行域的 SMNDC 中的参数放大进行了数学模拟。从非线性麦克斯韦算子的分岔点出发，分析了取决于分岔参数（偏置场强度和 SMNDC 中的电子浓度）的 SMNDC 中自振荡发生的条件。

Bifurcation Analysis of Electrodynamic Systems Containing Nonlinear Semiconductor Microstructures with Negative Differential Conductivity

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.
