Abstract Finite element method calculations
have been performed on a T-septum waveguide to investigate the possibility of
heating a lossy dielectric film mounted on a metal
surface. The results indicate that additional lossless dielectric loading is
required above the septum to provide the necessary electric field to heat the
lossy film. A parametric study reveals that
significant power deposition can occur in the film provided the permittivity
of the lossless dielectric loading is high. Measurements on an applicator
have shown that the temperature of a lossy film
painted on a metal surface can be increased by more than Key Words:
