ELECTROMAGNETIC FIELD DISTRIBUTION MEASURING METHOD AND APPARATUS THEREOF, COMPUTER PROGRAM AND INFORMATION RECORDING MEDIUM

摘要

An electromagnetic field distribution measuring method and an apparatus thereof capable of measuring an electromagnetic field distribution while considering variation with time in a measured value, a computer program and an information recording medium are provided. T 0 measure an electromagnetic field distribution in the vicinity of an object 1 to be measured, an electromagnetic field distribution measuring apparatus 2 is used. While scanning is being performed with a probe 3 at an arbitrary set of measurement coordinates in a predetermined measurement plane in a space in the vicinity of the obj ect 1 to be measured, a signal is detected during a predetermined time period at each of a plurality of sets of measurement coordinates in the measurement plane. In a signal time waveform computation section 12, the intensities of the electric field and the magnetic field are computed during the predetermined time period at each set of measurement coordinates in the measurement plane on the basis of the measurement coordinates at which the probe 3 is positioned and the signal detected with the probe. The distribution of amplitude probability in the predetermined time period at each set of measurement coordinates in the vicinity of the obj ect 1 to be measured is computed on the basis of the computed intensity and is mapped and displayed by an electromagnetic field distribution display section 16.
