Abstract

Interdependences are established between the parameters of the traditional description of relaxation polarization in a substance using the Debye equation and the parameters of impedance means of description. Using a model of a double-layer capacitor with leakage, patterns are found that describe the transition to strong relaxation, the disappearance of maxima in the frequency dependences of the tangent of the angle of dielectric loss, and the imaginary parts of the dielectric capacitance as functions of the ratios of resistances to capacitances of dielectric layers. The possibilities of frequency control of the conductivity and capacitance of heterogeneous dielectrics are analyzed. It is found that the negative capacitance module of a heterogeneous dielectric can be increased considerably if one of its layers has a negative capacitance.

弛豫极化时电介质电容和电导率的频率管理

摘要

使用Debye方程在物质中弛豫极化的传统描述参数与描述阻抗的参数之间建立了相互依存关系。使用带有泄漏的双层电容器模型，发现了描述向强弛豫过渡，介电损耗角正切的频率相关性最大值的消失以及介电电容的虚部为的图案。介电层的电阻与电容之比的函数。分析了频率控制异质电介质的电导率和电容的可能性。已经发现，如果异质介电层的一层具有负电容，则可以显着增加异质介电质的负电容模块。
