摘要

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 O₁ and O₂ from two ends of a measuring probe 20 and an output current R from a reference signal probe 30, the magnitudes of each of the output currents O₁ and O₂ and the phase difference of each of the output currents O₁ and O₂ from 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 probe 20 are calculated, and on the basis of the calculated results the electric field intensity and the magnetic field intensity are figured out.
