Method for dividing aerial reflecting plane graticule based on structure electromagnetic coupling

The invention discloses an antenna reflector mesh generation method based on structure electromagnetic coupling which is used for solving disjunction problem of mesh generation structure and electromagnetic request in present reflector antenna analyse. The mesh generation process includes: extracting reflector mesh through reflector antenna structure analyse model; changing reflector mesh model into regular geometry image according with upper limit of reflector working frequency; selecting standard mesh form according with reflector structure, and thinning selected standard mesh according with antenna working frequency request; changing thinned mesh into reflection mesh adaptive to geometry image; sampling in corresponding geometry image by using reflection mesh, and dividing three-dimensional mesh of antenna reflector, calculating electrical property parameter of reflection antenna. The method provided by the invention not only can meta-synthetic structure analyse and electromagnetic analyse, but also can greatly increase precision and efficiency of reflection antenna electromagnetic analyse calculation, and can be used for computer aided analyse and design for reflector antenna.
