  • Publication number: 20130231062
    Abstract: There are cases where electromagnetic waves radiated from a device influence another device, whereby the operation of the other device becomes unstable. The present invention provides a system having a detailed database of a device that radiates electromagnetic waves, so that a spatial distribution of electromagnetic waves radiated from an electric/electronic device can be computed, and the influence of the electromagnetic waves on another electric/electronic device can be evaluated.

  • Publication number: 20030231145
    Abstract: An electronic appliance displaying apparatus that, by implementing the following views, makes it possible to identify a wire, a component, or the like that generates an electromagnetic field. At first, the displaying apparatus derives electric-current distribution, electric-voltage distribution, electric-power distribution, and impedance distribution from magnetic-field distribution or electric-field distribution existing in vicinities of an electronic appliance, i.e., a target to be measured. Next, the displaying apparatus superposition-displays at least one of the above-described distributions on an image of the electronic appliance, CAD data thereon, layout data thereon, or circuit diagram thereof. Otherwise, the displaying apparatus displays, on plural views, at least one of the distributions and the latter data.
