Abstract

A method to estimate the source location based on the MUSIC algorithm is proposed and is applied to the electromagnetic field emitted by a microwave oven of the transformer-type. Since the frequency, the phase and the amplitude of the leakage field emitted by a microwave oven change with time, a detection method using the periodicity of the field is also proposed to obtain the phase distribution. Experimental results are shown of the estimation of the source location using the proposed method.
