DEVICE FOR APPLYING RF ENERGY TO A CAVITY
First Claim
1. An apparatus for applying RF energy to an object in a cavity, the apparatus comprising:
- a plurality of pairs of radiating ports, each pair comprising two radiating ports configured to emit RF radiation into the cavity coherently with each other; and
a plurality of electrically conductive elements, each positioned between two radiating ports constituting a pair of radiating ports,whereinthe electrically conductive elements are arranged such that RF radiation emitted by the plurality of pairs of radiating ports concentrates closer to the center of the cavity than in the absence of the electrically conductive elements.

Abstract
An apparatus for applying RF energy to an object in a cavity is disclosed. The apparatus may include a plurality of pairs of radiating ports, and a plurality of electrically conductive elements. Each pair of radiating ports may include two radiating ports configured to emit RF radiation into the cavity coherently with each other; and each electrically conductive element may be positioned between two radiating ports constituting a pair of radiating ports. The electrically conductive elements may be arranged such that RF radiation emitted by the plurality of pairs of radiating ports concentrates closer to the center of the cavity than that in the absence of the electrically conductive elements.
