A New Probe for Electromagnetic Compatibility and Electromagnetic Interference Detection

In this paper, a new probe for electromagnetic compatibility and electromagnetic interference detection is proposed, designed, and simulated. ANSYS HFSS software is used to design a 3D model and simulate the probe. The simulation result shows that the working frequency band is up to 3 GHz and spatial resolution is less than 4 mm for magnetic and electric field detection. These parameters show a good ability for locating the interference source. The new structure is able to measure the electric and magnetic field simultaneously, improve the efficiency of the near field detection greatly.
