An ignition apparatus for a combustor includes a microwave energy source that emits microwave energy into the combustor at a frequency within a resonant response of the combustor, the combustor functioning as a resonant cavity for the microwave energy so that a plasma is produced that ignites a combustible mixture therein. The plasma preferably is a non-contact plasma produced in free space within the resonant cavity spaced away from with the cavity wall structure and spaced from the microwave emitter.

Ignition apparatus comprising: a combustor; means for supplying a combustible mixture into said combustor; a body defining a resonator cavity therein; and a microwave energy source including a microwave emitter for emitting microwave energy into the cavity at a frequency within a resonant response of the cavity to produce a plasma in free space in the cavity; said body having at least one opening therein that permits the plasma to be exposed to the combustible mixture of the combustor for ignition thereof.
