Title
(EN) Electromagnetic wave analysis apparatus and design support apparatus
Abstract
(EN)

A design support apparatus of the present invention includes the following: an antenna electromagnetic field distribution input portion that inputs data indicating an antenna electromagnetic field distribution in the vicinity of electronic equipment; a board near electromagnetic field distribution input portion that inputs data indicating a board near electromagnetic field distribution as unwanted radiation noise radiated from a board of the electronic equipment; and a correlation value generator that generates a distribution of correlation values showing a correlation between the antenna electromagnetic field and the board near electromagnetic field based on the antenna electromagnetic field distribution data and the board near electromagnetic field distribution data.
