TL;DR: The detailed theoretical and simulated analyses in this paper has shown that it can be achieved to tranfer power without electrical wires using double loop antennas based on magnetic dipole theory.
Abstract: According to electromagnetic theory, there are several ways to tranfer power without electrical wires. We found another method for the purpose based on magnetic dipole theory, the detailed theoretical and simulated analyses in this paper has shown that it can be achieved. We used one loop antenna for transfer and the other for receiving, and found the system efficiency saturates when the opreationg frequency reaches 8MHz, the maximal output power is about 0.02mW. The low efficiency of the magnetic dipole makes the double loop antennas transfer efficiency and output power not ideal. Therefore the suggestion of the experiment is using strong directional helical antenna to get a better result in the future.

TL;DR: In this paper, a coupling model was built up for two coils in arbitrary spacing, and the relationship between coupling coefficient and axial, lateral and pitch misalignments was numerically analyzed.
Abstract: In the wireless power transmission system for remotely implanted MEMS,the coupling coefficient is one of the most crucial factors affecting transmission efficiency.A coupling model was built up for two coils in arbitrary spacing.A formula for calculating coupling coefficient was induced.The relationship between coupling coefficient and axial,lateral and pitch misalignments was numerically analyzed.The results met with experiments quite well.By this method,finally,two ways of laying transmitting coil modes were compared.
