Abstract (in Japanese) (See Japanese page) 
(in English) There prevails a confusion on the analysis of electrically coupled WPT system due to the misunderstanding in the duality between the electric and magnetic couplings. The present report tries to solve the misunderstanding and show the right transformation and equivalent circuit. The latter enables to fabricate the WPT circuit effectively by the kQ-product theory through the Z or Y parameter measurement using a 2-port VNA.
