Plasma antenna simulation method and system

Abstract

The invention discloses a plasma antenna simulation method and system. The method comprises the steps of first, acquiring physical field information to which a plasma antenna relates in working, and determining coupling equations of multiple physical fields according to the related physical field information; then determining performance parameters of the plasma antenna according to the coupling equations; and finally, building a plasma antenna physical simulation model, and running the plasma antenna physical simulation model according to the performance parameters and physical field information, so as to obtain a simulation result. When the plasma antenna physical simulation model runs, the fact that the plasma antenna relates to the coupling effect of multiple physical fields in working is taken into consideration, so that parameters are not set only for the plasma antenna material, the plasma antenna simulation results are more accurate, and the simulation errors are reduced.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a plasma antenna simulation method and system coupled with multiple physical fields. Background technique [0002] Plasma exists widely in the universe. It is the fourth form of matter after solid, liquid, and gas. It is composed of a large number of charged particles, but it is electrically neutral on a macroscopic scale. With the in-depth study of plasma, more and more people pay attention to the use value of plasma. Since the 1960s, some developed countries have begun to use plasma in military fields, such as plasma stealth and plasma coating materials. [0003] Plasma antenna is a typical application of plasma, which uses plasma instead of ordinary metal to conduct and radiate electromagnetic waves. Because the plasma antenna only exhibits conductivity when it is working, it can effectively reduce the radar scattering cross section, has good stealth performance, and has...

Problems solved by technology

However, this setting method only sets a single parameter for the plasma material, and does not take into account the interaction of multiple physical fields at the same time when the plasma antenna is working, such as particle flow field, electromagnetic field, energy field, etc.

In general, the current simulation method still has the problem of inaccurate simulation results of the plasma antenna and large errors.
