Abstract

The purpose of this study is to design a single-mode cavity which operates at 2.45 GHz and is optimized for sintering ceramics. Simulations were carried out for two types of dielectric configurations. In the first case the dielectric cylinder fills the whole length of the cavity, and in the second the dielectric cylinder occupies only a fraction of it. On these two configurations an optimization procedure was carried out, the object of which was to maximize the electrical energy stored in the dielectric and minimize the spatial variations of the electric field. Results suggest that such an optimum does exists and that the former configuration proves to be a more efficient means of heating
