1. A clothes dryer, comprising:
- a cavity adapted to receive at least one item of clothing;
at least one RF feed which feeds RF energy into the cavity;
a spectral imaging module adapted to provide a spectral image comprising input efficiency to the cavity as a function of frequency; and
a controller that controls one or more characteristics of the RF energy to heat a liquid within and/or on fibers of the at least one item of clothing, wherein the controller reduces amounts of energy directed to problem areas in the spectral image.

Abstract
A clothes dryer includes a cavity adapted to receive at least one item of clothing, at least one RF feed which feeds RF energy into the cavity, and a spectral imaging module adapted to provide a spectral image comprising input efficiency to the cavity as a function of frequency. A controller controls one or more characteristics of the RF energy to heat a liquid within and/or on fibers of the at least one item of clothing, in which the controller reduces amounts of energy directed to problem areas in the spectral image.
