Electromagnetic wave propagation property analysis method and analysis system

Abstract

The invention discloses an electromagnetic wave propagation property analysis method and an analysis system. That prediction and analysis are performed on radio wave propagation property in indoor environment can be achieved. Research and analysis can be performed on indoor wireless communication property through initialization modeling of indoor communication environment, establishing of an emission ray tube, intersection test of a ray tube, determination of a reflection ray tube, judgement of a receiving ray tube and calculation of field strength at receiving points based on an shooting andbouncing ray method and a mirror image method (SBR/IM) in a ray tracing method. Through the calculation of the analysis system, a time domain waveform diagram of an emission signal, a received signalpower diagram, a path loss diagram and propagation animation demonstration of electromagnetic waves in the indoor environment can be obtained. The method and system are convenient, fast and economic in operation, have good auxiliary predictive functions for the propagation and distribution of the electromagnetic wave in buildings, and play an important role of the placing and optimization of indoor signal emitters.
