Abstract
A method and apparatus for measuring an electric field distribution according to the present invention calculates a distribution of electric field intensity and its direction at arbitrary positions on the surface of the electronic apparatus or its circumference with use of data of measurement positions and measurement results of a potential distribution on a surface of an electronic apparatus. Further, it clearly indicates a flow of electromagnetic energy on the surface or in the circumference of the electronic apparatus by applying mathematical treatments to a magnetic field distribution at circumferential positions of the electronic apparatus. Thus, a distribution of high-frequency electric field generated from the electronic apparatus is measured with high accuracy.
