Abstract:
An electromagnetic wave analyzing apparatus having an electromagnetic wave analyzing unit for analyzing electromagnetic waves radiated from an appliance, on the basis of net pattern information concerning a net pattern obtained by modeling said appliance under analysis, said apparatus comprising:a coordinates data extracting unit for extracting, from said net pattern information, coordinates data defining the coordinates of each of terminal points of a plurality of segments constituting said net pattern; and a net pattern smoothing unit for dividing said net pattern, based on the coordinates data extracted by said coordinates data extracting unit, into object sections each containing a prescribed number of segments so that the length of each of said object sections is not greater than a predetermined maximum length, and for carrying out smoothing of said net pattern for each object section, by replacing said prescribed number of segments contained in said object section with a single straight line or a plurality of straight lines smaller in number than the number of said segments, wherein, the coordinates data on which said smoothing has been completed is input to said electromagnetic wave analyzing unit for calculation of the electromagnetic field intensity of said electromagnetic waves, wherein said net pattern smoothing unit carries out said smoothing for said each object section by selecting an arbitrary intermediate point located between coordinates defining a start point of said object section and coordinates defining an end point thereof, and by setting the coordinates of said intermediate point so that the sum of the distance between said start point and said intermediate point and the distance between said intermediate point and said end point is equal to the combined length of said prescribed number of segments contained in said object section, and the coordinate data containing the coordinates of said start point, said intermediate point, and said end point of said object section, for which said smoothing has been completed, is input to said electromagnetic wave analyzing unit.
