Abstract:
1. An electromagnetic wave measuring apparatus comprising: an electromagnetic probe section at least integrally including a first loop probe forming a first loop plane, a second loop probe forming a second loop plane perpendicular to the first loop plane, and a third loop probe forming a third loop plane perpendicular to the first and second loop planes; a stage section, on which an object to be measured is mounted, for placing the object to be measured under the electromagnetic probe section; a driving section operable to cause a movement of at least one of the electromagnetic probe section and the stage section relative to the other; an electromagnetic wave level generating section at least including first to third generating sections operable to detect induced electric signals from the respective first to third loop probes, and operable to generate first to third electromagnetic field level information indicating intensities of electromagnetic waves perpendicular to the respective first to third loop planes; and a calculation processing section operable to calculate three-dimensional electromagnetic field level information indicating intensities of three-dimensional electromagnetic waves by calculating a root sum square of the first to third electromagnetic field level information generated by the electromagnetic wave level generating section.
