The WR-340 waveguide (a) and slotted waveguide (b) used in HEPHAISTOS Microwavecavity Microwave cavity is a type of resonator with a closed metal structure, which is the main part of a microwave heating system [Mer98]. Mi- crowaves transmitted from waveguides will propagate through the cavity space, and they will also get reflected by the walls of the cav- ity, or get absorbed by the load that is put within the cavity. The microwave energy is gradually dissipated, and the load eventually gets heated. A microwave cavity could be constructed into different shapes, including rectangular, circular, hexagon (HEPHAISTOS), oc- 27 g
