Patent ID: 8874417

Claim:
A computer implemented method of deriving a scattered wave comprising the steps of: calculating, using a computer, a first scattered wave from a scatterer at a predetermined position by using a predetermined electromagnetic wave entering the scatterer; calculating, using the computer, a second scattered wave from a spherical nanoparticle cluster at the predetermined position by using T-matrix method when the predetermined electromagnetic wave enters the spherical nanoparticle cluster in a state where the spherical nanoparticle cluster containing a plurality of spherical nanoparticles is arranged inside a region that has the same shape and size as those of the scatterer; determining, using the computer, a condition of the plurality of spherical nanoparticles so that the first scattered wave is equal to the second scattered wave; and obtaining, using the computer, the scattered wave from the scatterer at an arbitrary position when an arbitrary electromagnetic wave enters the scatterer, based on the determined condition of the plurality of spherical nanoparticles.
