Parameter-variable precision plasma antenna radiation performance simulation method

Abstract

The invention discloses a parameter-variable precision plasma antenna radiation performance simulation method and aims to realize detailed analysis on relation between plasma antenna radiation performance and plasma physical property to improve simulation precision. The method includes: firstly, determining a physical model of an antenna and incident electromagnetic wave frequency of the antenna according to a system and an operating frequency of the antenna, substituting into a Drude dispersion equation, and taking the fact that electrical conductivity can be represented by plasma relative dielectric constant values as limits to obtain plasma frequency omega pe and plasma collision frequency v by calculation; adopting CST software for setting up an antenna model which is a dispersion model, setting parameters of the dispersion model according to the plasma frequency omega pe and the plasma collision frequency v, and starting simulation to obtain an antenna radiation performance result; finally checking the antenna radiation performance result to judge whether the result meets requirements or not, and if not, re-determining a group of parameters and repeating the steps.

Description

technical field [0001] The invention relates to the technical field of plasma antenna simulation, in particular to an accurate plasma antenna performance simulation method with variable parameters. Background technique [0002] Plasma (Plasma) is an unbound macroscopic system composed of a large number of charged particles. It contains free electrons, free ions, and neutral particles may also exist. It is the fourth state of matter after solid, liquid, and gas. , is a high-energy aggregate state of matter in an ionized state. Usually, in this condensed state, the negative charge of electrons is equal to the total number of positive charges of ions, and it is neutral macroscopically, so it is called plasma. Plasma is a common form of matter in the universe, and they have a great influence on the propagation of electromagnetic waves. Under certain conditions, plasma can reflect electromagnetic waves; under another condition, it can absorb electromagnetic waves. [0003] The...
