ELECTROMAGNETIC FIELD DISTRIBUTION MEASURING METHOD, APPARATUS FOR THE METHOD, COMPUTER PROGRAM AND INFORMATION RECORDING MEDIUM
First Claim
1. An electromagnetic field distribution measuring apparatus that detects intensity of either an electric field or a magnetic field, or both, in an arbitrary frequency band of an object to be measured so as to measure an electromagnetic field distribution, comprising:
- a detecting section that detects the intensity in a space in the vicinity of the object to be measured at a plurality of measurement positions during a predetermined measurement time period;
a computing section that computes an amplitude probability distribution of the intensity detected by the detecting section during the measurement time period; and
a mapping section that maps the distribution of values of the intensity in an arbitrary measurement area by using an intensity value of the amplitude probability distribution when a probability is a predetermined value at each of the plurality of measurement positions.

Abstract
Electromagnetic field distribution is measured by considering time variations of a measured electric and/or magnetic field value. In response to scanning performed with a probe at an arbitrary set of measurement coordinates in a predetermined measurement plane in the vicinity of an object to be measured, a signal is detected at each of plural sets of coordinates in a measurement plane. Electric and magnetic fields are computed during a measurement time period at each set of measurement coordinates in the measurement plane based on measurement coordinates where the probe is positioned and the signal is detected with the probe. Amplitude probability distribution during the time period at each set of measurement coordinates in the vicinity of the object is computed based on the computed intensity, then mapped and displayed.
