Abstract(in English) This paper presents a standing wave elimination technique on an electrified floor for continuous power transfer to an electric cart in motion exploiting left-handed circuits. Before employing that technique, we first constructed an electrified floor in regular structure. We measured S-parameters of the system at nine positions and calculated η_ for estimating a standing wave node. Exhibited η_ are 0~46% and η_ vanishes at 1/4 λ from open terminal of electrodes. We then designed and prototyped left-handed circuits and inserted them into electrified floor periodically. Measured η_ increased to 42~65%. This verifies that the circuits eliminate standing wave on a electrified floor. Using the electrified floor, we successfully performed continuous power transfer to an electric cart in motion.
