The Microwave Oven Thermal Field Uniformity Increasing by Using Powermeter

The microwave oven qualities improvement can be achieved, if use a powermeter. Extracting information about the passing power from the sensor signals in the powermeter can be performed by determining the passing power as a geometric mean of the sensor signals. The main advantage of this approach is ease of automation. The limitations of the passing power calculating algorithm as a geometric mean of two sensors signals are that mathematically rigorous expressions. It can be obtained only if two sensor signals are taken at the maximum and minimum of the standing wave. When the sensors was not placed in the maximum and minimum of the standing wave, the error appears. An amendment was made, and the non-excluded residual was estimated.
