Abstract
The research on the radio-frequency wireless energy transmission in the cavity has just started at present, which is limited to the feasibility and loss analysis of fixed size and working frequency. This paper deeply studies the point-to-point wireless energy transmission model in the cavity, analyzes the field and the energy loss energy of the transmission in the cavity. Based on the electromagnetic simulation software HFSS, the cavity simulation model is used to obtain the different influencing factors of energy transmission. The results show that the greater transmission efficiency and working bandwidth can be obtained when the transmitting and the receiving antenna are in the diagonal of the rectangular cavity when the TM220 wave is transmitted in the cavity. The longer the receiving antenna length is, the lower the transmission efficiency is. In addition, when the cavity size is larger and the resonant frequency is low, the loss is not great.
