| Abstract | ||
| The efficiency of a WPT system greatly depends on both the geometry and operating frequency of the transmitting and receiving structures. Genetic optimizations algorithms are presented to prepare the proposed design parameters using MATLAB to optimize the link efficiency. Single and double layer PSCs are optimally designed with minimal proximity losses effect. In this paper, we used the benefit of a double layer technique to miniaturize the receiver PCS size. The proposed single layer (10×10) mm2 and double layer (8×8) mm2 PSCs are validated and simulated using HFSS 15.03 software at a frequency of 13.56MHz in both cases of the air, and human biological skin tissue as intermediate material between the transmitter and receiver PSCs. The calculated and simulated results of both proposed receiver PSCs are compared for both cases of intermediate materials for their efficiency behaviors. The results show that in the case of biological tissue, the deterioration in PTE using 8mm double layer receiver is only 6.5 % (PTE =70.96%), which is less than 13.5 % (PTE=68.6%) using single layer 10mm receiver. A comparative survey has been done for similar works of different authors in the last decade. In comparison with other works, the proposed double layer (8×8) mm2 PSCs is smaller in size and more efficient for use in the IMDs. | ||
