Abstract

The invention discloses a scattered field solving method applied to a simulated FSS structure. Compared with a traditional triangular-tetrahedron and RWG-SWG primary function VSIE method for solving the scattering field, the method solves the problem of frequency deviation, the number of unknown quantities and the memory overhead of calculation can be greatly reduced, and meanwhile the solving efficiency is higher. According to the method, the design of the FSS structure can be guided more efficiently and accurately, analogue simulation of a large-scale array is facilitated, and the method haspractical engineering application value.

Description

technical field [0001] The invention relates to the field of electromagnetism, in particular to a method for solving a scattered field applied to a simulated FSS structure. Background technique [0002] Frequency selective surface (FSS) is widely used in stealth technology. It is a two-dimensional periodic structure, essentially a spatial filter, composed of resonant metal units periodically arranged. FSS has selective permeability to electromagnetic waves of different frequencies. It is usually divided into two types: patch type and aperture type. angle of incidence, etc. In practical engineering applications, FSS is usually composed of a metal plate and a dielectric substrate. On the one hand, the physical strength of the FSS is increased. On the other hand, the processing method of PBC plate or skin coating is used, and the manufacturing process is relatively easier. There are generally two ways to load the medium: one is unilateral loading, and the metal FSS is attache...
