A guided wave applicator comprising two electrically conductive waveguide walls and a waveguide dielectric. The volume of the waveguide dielectric is composed of non-gaseous dielectric material and is positioned between the two waveguide walls. The waveguide dielectric includes first and second longitudinal ends and includes first, second, third and fourth sides extending longitudinally between the two longitudinal ends. The first waveguide wall is positioned so that it covers the first side of the waveguide dielectric, and the second waveguide wall is positioned so that it covers the second side of the waveguide dielectric. In operation, electrical power can be supplied to one or both longitudinal ends of the waveguide dielectric, whereby the power can be coupled to a plasma through the exposed sides of the waveguide dielectric.
