Abstract
A radio frequency applicator comprises an open-ended, hollow waveguide having an aperture therein. A solid insert is positioned within the waveguide. The solid insert has a recess formed therein that is aligned with the aperture. Filler material is provided between facing surfaces of the waveguide and the insert to fill gaps therebetween. A radio frequency (RF) source extends through the aperture and into the recess and is configured to generate RF energy pulses.
