Abstract
A capacitor includes a first plate and a second plate parallel to the first plate. An RF source includes a first line and a second line through which RF is fed. The first line is electrically connected to the first plate. The second line is passed through the first and second plates and then looped around the first and second plates, and the pass and loop of the second line is repeated at least once. The second line is then passed through the first plate and electrically connected to the second plate to form a capacitor having negative capacitance.
