1. A method of drying an object in a cavity using RF energy radiation, the method comprising:
- applying RF energy to the object;
obtaining a spectral image, comprising input efficiency to the cavity as a function of frequency, based on coupled power between first and second antennas; and
adjusting the application of RF energy based on the spectral image.

Abstract
A method of drying an object comprising, providing an object into an RF cavity; applying broadband RF energy to the object in controlled manner which keeps the object within a desired temporal temperature schedule and within a desired spatial profile; and terminating the drying when it is at least estimated that a desired drying level is achieved.
