Summary:
In this work, a comprehensive study on seal effects on WPT systems via magnetic resonance coupling is conducted by virtue of full-wave electromagnetic solutions. Five sealing materials, Cu, ABS, earth, glass and sea-water, are discussed. It is shown that the resonant frequencies of the WPT systems sealed by the five materials change a little or unchanged. ABS and glass have little seal effects on the efficiencies of WPT systems. The efficiencies of WPT systems sealed by Cu material, earth material and sea-water material will decrease dramatically, and the WPT systems sealed by Cu can hardly transfer energy wirelessly. Therefore the WPT systems can be protected by sealed with ABS or glass materials, and should avoid to be sealed with Cu material. The results are also verified by experiments.
