The method of building equivalent electromagnetic environment

In order to improve the fidelity and controllable of electromagnetic environment(EME) building, and build realistic EME for testing and researching the complex EME effect on the electronic information systems, this paper puts forward Equivalent building methods of complex EME based on the meta-elements. First, the paper analysis the domestic and foreign research which presents the current situation and the demand, and then puts forward the methods and expounds the core idea of basing the meta-elements to realize the equivalent EME building. Further it introduces extraction method of the electromagnetic signal environment meta-elements, and builds the description of them. In the end, it put forward the method and process to build the complex EME based on the meta-elements. This research results provide the technical support to improve the level of test EME building.
