Problems solved by technology

[0004] But at present, it can only be calculated for the situation of flat plate structure and uniform distribution of electric field, and the diffusion of different electrons cannot be considered under the condition of non-uniform field
Therefore, it is not possible to calculate for microwave components with non-uniform field distribution

Abstract

A method for determining number of multi-carrier microdischarge secondary electrons distributed in an inhomogeneous field includes: firstly, equally dividing a cross section of an inhomogeneous field distribution area; secondly, subjecting each subdivided area to statistics and accumulation of multi-carrier microdischarge secondary electrons to acquire the electron number of each subdivided area; thirdly, subjecting different areas to redistribution of the secondary electron number according to the diffusion property of the secondary electrons; fourthly, taking the distributed secondary electron number as an initial number to subject each area to statistics and accumulation of secondary electrons again, thereby obtaining the number of the multi-carrier microdischarge secondary electrons distributed in the inhomogeneous field.

Description

technical field [0001] The invention relates to a method for determining the number of secondary electrons of multi-carrier micro-discharge with non-uniform field distribution, and belongs to the field of microwave device micro-discharge. Background technique [0002] At present, most satellites work in the multi-carrier mode. The filter of the duplexer in the communication satellite transceiver system is a common channel for signal transmission and is in a high resonance state. There are problems in the analysis and design of micro-discharge under the excitation of multi-carrier signals. [0003] The most important difference between the multi-carrier microdischarge analysis and the single-carrier case is that the amplitude of the excitation signal changes rapidly with time depending on the initial phase. The threshold analysis of multi-carrier microdischarge in space microwave components needs to determine the minimum power that can excite microdischarge and its correspond...
