Abstract
A microwave system having a microwave source that generates microwave signals for regenerating a diesel particulate filter (DPF) includes a sampling device that samples a power level of reflected microwave signals from the DPF and a regulator module that communicates with the microwave source and the sampling device. The regulator module further adjusts operation of the microwave source based on the power level of the reflected microwave signals and a predetermined power threshold.
