摘要：
A system for preventing freezing of crops within a volume includes a pluralityof RF radiators configured to radiate RF energy into the volume. A height, a spacing,an output power, a vertical beam angle, a vertical beam width, and a horizontalbeam width of each one of the plurality of RF radiators is selected to result inan average RF power density taken about three dimensions within the volume sufficientto prevent freezing of a substantial portion of the crops, and also to result ina peak-to-peak variation of RF power density taken about two dimensions in a horizontalplane within the volume and at heights below a predetermined height to be lessthan a predetermined percentage of an average RF power density taken about thetwo dimensions.
