Claim:
1. A gas turbine, comprising: a combustion chamber with a cavity configured to receive and burn a fuel-air mixture, wherein the combustion chamber is an annular combustion chamber that extends annularly about a rotational axis of the gas turbine; and a microwave source configured to produce microwave radiation, wherein the gas turbine is configured to guide the microwave radiation into the cavity of the combustion chamber to support the combustion of the fuel-air mixture in the combustion chamber, wherein the gas turbine comprises an annular first chamber attached to the combustion chamber, so as to be disposed outside of the combustion chamber from a perspective of the rotational axis of the gas turbine, and extending annularly about the rotational axis of the gas turbine, wherein an annular second chamber is disposed inside the first chamber, and extending annularly about the rotational axis of the gas turbine, wherein a plurality of microwave-permeable windows is included in a limiting surface between the combustion chamber and the second chamber and are arranged annularly about the rotational axis of the gas turbine, wherein the second chamber has a plurality of slits that are arranged annularly about the rotational axis of the gas turbine and opposing the microwave-permeable windows, and wherein the microwave source is connected to an antenna that projects into the first chamber.
