Abstract
A method of heating a load in a cavity using microwaves wherein the microwaves provide mode fields in the cavity includes obtaining a desired temperature pattern within said cavity based on information about regions of the load. A heating pattern in the cavity is determined and comprises zones of different intensities corresponding to the desired temperature pattern. A zone of higher intensity in the determined heating pattern corresponds to a region of higher temperature in the desired temperature pattern. The method also includes controlling one or more independently controllable microwave generators or feeding ports so the mode fields form the determined heating pattern and thereby heat the load according to the desired temperature pattern.
