Method, apparatus, and program for measuring an electromagnetic field and medium recording the program

Abstract

Provided is a method, apparatus and program for calculating an electric-field vector that allows for grasping the intensity, direction and phase of electric field on a scanning plane for an appliance, and a medium recording the program. An electric-field vector at an origin is calculated, based on potential-difference vectors in respective coordinate directions calculated depending upon a detected signal of at least a magnitude and phase of an electric-field component current by arranging a scanning electric-field sensor at an origin of a desired coordinate system established near an object-to-be-measured, signals detected at respective coordinates by sequential movement to desired coordinates on respective coordinate axes, and a detected reference signal of at least a magnitude and phase of a current by fixedly arranging a fixed magnetic-field sensor close to the object-to-be-measured, and distances between coordinates calculated based on the coordinates the scanning electric-field sensor is arranged and the origin.
