This paper introduces a novel method of waveguide-mode wireless power transfer (WPT) in a shielded space with an aperture plane. First, it is shown that the simplified model of the engine compartment behaves as a ridge waveguide. Next, the WPT efficiency at the resonant frequency of the dominant mode in the ridge waveguide is discussed using a monopole probe and a helical probe. The results obtained from these simulations and measurements indicate a possibility that WPT efficiency can be improved by our method. Finally, it is experimentally demonstrated that the line-of-sight and non-line-of-sight wireless sensors can operate using our method.
