The present invention is directed to a method for producing a cured tire filling composition and the composition resulting from such a method. In a first driving state, the first selective conduction path 119 is allowed to conduct and the second selective conduction path 121 is left open, so that a main beam is emitted in a direction 123a of the second selective conduction path 121 as viewed from the feeding site 113. The inductor is connected between the pair of flat plates, and the connection channel is configured to connect electrically the at least one of clock signal extraction points to an external circuit.
