Abstract :
High sensitivity electromagnetic field distribution mapping is useful for analyzing intra-system EMC issues. We have developed a high sensitivity electromagnetic sensor for this mapping. The sensor uses the resonance of an inductive loop and a chip capacitor. The sensitivity of a system using this sensor is improved by about 20 dB compared to a conventional one. This paper studies the use of this resonance sensor for electromagnetic field mapping.
