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.
