Abstract (in Japanese) (See Japanese page) 
(in English) We propose here a transparent electromagnetic shield using tap water. We have obtained a big shield effect for the leakage electric field from the WPT system by using the reflection due impedance mismatching between the water sheet and the free space where there is a wave source. In addition, the loss to a system is quite small by its selective shield effect that hardly influences the magnetic field used for power transfer. Aiming that this shielding method could be adopted widely, we will show the simulation and measurement of the effect of the present selective shield method which uses water for the EMC solution to a WPT system for the robot fish which our study group is now developing.
