Analysis of electromagnetic wave propagation characteristics in rotating environments

During the parameter acquisition of rotating components, wireless data transmission is an efficient way to resolve data transmission problem in rotating environments, and the design of wireless data transmission system is based on EMWP (electromagnetic wave propagation). In this paper, EMWP characteristics in rotating environments are preliminarily studied in order to provide a strong theoretical support for developing high-performance rotating component radio monitoring system. In particular, the Doppler frequency shift and the EMW polarization characteristics in rotating movement are fundamentally analyzed. Finally, a test bench of rotating component is built to test EMW propagation characteristics of both stationary transmitter and rotating transmitter.
