Abstract

Frequency spectra of the magnetron of the Whirlpool - Talent microwave oven with a cuboidal glass object located in the centre of the turntable are measured with a spectrum analyser for different angular positions of the object. Then, electromagnetic software is used to calculate the amplitude of the reflection coefficient as a function of frequency in the frequency band between 2.4 GHz and 2.5 GHz, for different angular positions of the glass object. By comparing calculated resonant frequencies with the measured leakage characteristics, conclusions regarding the actual operating frequency of the microwave oven are drawn. This provides valuable suggestions for further modelling activities in the area of microwave power applications.
