ABSTRACT:
A measuring method for electromagnetic field intensity capable of easily and accurately measuring, with a compact and simple facility, each of the electric field component and the magnetic field component of an electromagnetic field formed in space is to be provided. By simultaneously measuring output currents O1and O2from two ends of a measuring probe20and an output current R from a reference signal probe30, the magnitudes of each of the output currents O1and O2and the phase difference of each of the output currents O1and O2from the output current R are measured, on the basis of the measurements the electric field component current generated from the electric field and the magnetic field component current generated from the magnetic field upon the measuring probe20are calculated, and on the basis of the calculated results the electric field intensity and the magnetic field intensity are figured out.
