Abstract：Wireless power transmission has become a popular topic in recent years. Along with the fast development of the technology in various fields, the electromagnetic environment is getting complicated. This paper focuses on the interaction that comes from adjacent devices when several equipments work simultaneously in relatively small rooms. The system parameters and distribution of electric-magnetic fields are indicated by finite element emulation software. At last, the experiments confirmed that a set of system resonators has electromagnetic coupling with adjacent ones and a series of resonator parameters are changed, which causes resonance point deviation and reduces transfer efficiency.
