On the channel modeling of intelligent controllable electro-magnetic-surface

One of the crucial aspects in the 6G research is to realize the intelligent reconfiguration of radio channel by deploying intelligent electro-magnetic-surfaces and the channel modeling in this area is the fundamental for future deployment and planning of electro-magnetic-surfaces as well as the analysis of coverage, capacity and other performance of network. In this article, the methodology of channel modeling is presented based on map-based hybrid channel model, ray tracing technology and the model of electro-magnetic surface reflection, which is suitable for the electro-magnetic-surface being deployed in a complex scenario. The proposed algorithm simplifies the modeling procedure and decreases the calculation loaded by modeling the intelligent electro-magnetic-surfaces as the multi-vitural logical base stations stimulated by multi-imping waves, which establishes the basis for the research of intelligent reconfiguration on radio propagation environment.
