Abstract
A plasma torch employs a dielectric resonator excited at separate locations with phase shifted signals to provide more uniform current flow through the resonator. High-power operation is possible while protecting the dielectric by using a combination segregated spiral flow and linear flow cooling air at different rates. Microwave leakage from the plasma resonant chamber is contained by conductive metal chokes.
