Claim:
1. An internal combustion engine comprising: an internal combustion engine body formed with a combustion chamber and an ignition device igniting an air-fuel mixture in the combustion chamber and configured to perform repetitive combustion cycles, including ignition of the air-fuel mixture by the ignition device and combustion of the air-fuel mixture, thereby generating a flame; an EM wave-emitting device that emits EM radiation to the combustion chamber at a plurality of times after the ignition of the air-fuel mixture, a plurality of receiving antennas comprising first and second receiving antennas located on a zoning material that defines the combustion chamber, where the antennas resonate to the EM radiation emitted to the combustion chamber from the EM wave-emitting device, the second receiving antenna being at a location closer to the ignition device than the first receiving antenna, and a switching means which switches the receiving antenna resonating to the EM radiation emitted to the combustion chamber from the EM wave-emitting device between the first and second receiving antennas during each combustion cycle such that the second receiving antenna resonates to the EM radiation at an earlier timing than the first receiving antenna in the combustion cycle.
