Design optimization using dielectric slab for efficient microwave heating

Design optimization using dielectric slab for efficient microwave heating

In this paper, usage of a dielectric slab on the top and bottom sides, on the top side, and on the bottomside of a clay sample was presented as a means of improving heating efficiency in multimode applicator. In order toaccomplish the optimization procedure, we used four different dielectric slab types having different thickness values. Thesimulated results show that by using additional dielectric slab it is possible to increase the electric field intensity insidethe applicator and obtain higher power absorption rates within the sample and high-efficiency designs.
