Claim:
1. A method of igniting a combustible material in a combustion chamber of a combustion engine, comprising: receiving an electrical stimulus from an ignition control system associated with the combustion engine; generating a waveform in a waveform generator capable of triggering an RF oscillation in a quarter wave coaxial cavity resonator in response to said electrical stimulus; coupling said waveform to said quarter wave coaxial cavity resonator through an angularly positioned loop coupling to trigger said RF oscillation in said quarter wave coaxial cavity resonator, said loop coupling being angularly positioned within said quarter wave coaxial cavity resonator to match an impedance between said waveform generator and quarter wave coaxial cavity resonator; generating a standing wave in said quarter wave coaxial cavity resonator using said RF oscillation, said quarter wave coaxial cavity resonator being operably adapted to produce a corona near a center conductor when said standing wave is present; producing plasma from said corona near said center conductor of said quarter wave coaxial cavity resonator; and igniting the combustible material in the combustion chamber of the combustion engine using said plasma.
