Abstract In this paper the design of a
handheld light applicator for microwave heating is presented. The applicator is
made of an array of resonant longitudinal slots cut on a broad wall of a
rectangular waveguide, and it is covered by a cylindrical lens made of
Plexiglas with a permittivity of 2.53. The geometrical optics approach is
used as initial approximation to establish the lens profile. It allows for
the shaping of the slotted waveguide’s radiation pattern into a desired
output pattern in the transversal plane. Three-dimensional simulation results
show that the applicator performance can be improved at 2.45 GHz by using a
homogeneous dielectric lens. Key Words: Dielectric lens, microwave heating, geometrical optics |
