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...
The authors have developed an adjacent electromagnetic field distribution measurement system using a unique sensor and three-input phase-difference measurement technique that can simultaneously measure electric and magnetic field (magnitude and phase) distributions up to 3 GHz. Electric and magnetic field distributions measured by this new system have produced superior results and more useful information...
