Abstract :
A planar microwave applicator consisting of a grounded dielectric layer excited by a current line has been theoretically and numerically studied using both a longitudinal spectral representation and a steepest-descent representation. The role of leaky-waves in the description of the near field, and their usefulness in understanding power deposition patterns has been investigated and clarified. Simple design criteria have been found and a general approach has been indicated, that can be applied to the various practical cases
