Propagation Modeling for Underwater Magnetic MISO Wireless Power Transfer
In the underwater scenario, the multiple inputs and single output (MISO) technology can greatly enhance the wireless power transfer (WPT) range. In this paper, we investigate the wireless power propagation model for MISO based underwater WPT (UWPT). Experiments are conducted to record the transmission characteristics of the system, using the voltage and phase to model the coupling state of the system. We measure the voltage and phase at different positions in a plane 55mm away from the transmitters, and the experimental results demonstrate that the system has a good transmission performance in most areas of the measurement range. Compared to the experiment with the same setups in the air, the UWPT system can transmit more power and longer distance.
