Patent ID: 7826989

Claim:
A non-transitory computer-readable medium having instructions stored thereon, such that when the instructions are read and executed by a processor, the processor is configured to perform an electromagnetic field analysis by performing the steps of: a first electromagnetic field analysis step of dividing a first analysis space surrounded by a closed surface and including a first wave source of an electromagnetic field in a first cell size to determine a first electromagnetic field distribution inside of said closed surface, on said closed surface and close to the outside of said closed surface; and a second electromagnetic field analysis step of dividing a second analysis space including said first analysis space in a second cell size larger than said first cell size to determine a second electromagnetic field distribution inside of said closed surface, and on said closed surface, and a third electromagnetic field distribution outside of said closed surface, said second electromagnetic field analysis step including a step of determining the second electromagnetic field distribution, where a differential electromagnetic field distribution between said third electromagnetic field distribution and said first electromagnetic field distribution close to the outside of said closed surface is a second wave source, for inside of said closed surface, and on the closed surface, and said second electromagnetic field analysis step including a step of determining the third electromagnetic field distribution, where an electromagnetic field distribution obtained by synthesizing said first electromagnetic field distribution and said second electromagnetic field distribution on said closed surface is a third wave source, for outside of said closed surface.
