Equivalent field strength estimation method and radiation interference measurement device

摘要

PROBLEM TO BE SOLVED: To estimate an equivalent electric field intensity on each axis on a predetermined position distanced by more than the radius of a loop antenna.SOLUTION: A step S101 performs calculating based on number 1 a current value in a case where a micro magnetic dipole is arranged in a large loop antenna system. Then, a step S102 performs calculating an equivalent electric field intensity at a distance of 3 m, for example, when the micro magnetic dipole is arranged at a height of 1.3 m from a ground plane using numbers 2, 3, 4, and 5. A step S103 performs acquiring a three-row and three-column transformation matrix with respect to the height and distance of the one example from a result obtained by the step S102. Further, a step S104 includes disposing a sample in the large loop antenna system, measuring output values Ix, Iy, Iz of the large loop antenna system, and then estimating an equivalent electric field intensity by substituting the output values into number 6.SELECTED DRAWING: Figure 3
