To provide an easily-operable organism electromagnetic environment estimation device, a method and a program capable of estimating the organism electromagnetic environment regardless of the distance between an electromagnetic radiation wave source and a scatterer.
Model data of the scatterer and the electromagnetic radiation wave source, an application region of method of moments (M0M) including the electromagnetic radiation wave source, data for specifying the application region of a scattering field type finite-difference time-domain (FDTD) method including the scatterer and the application region of M0M, or the like are prepared beforehand. A current distribution caused by a feeding voltage to the electromagnetic radiation wave source is determined by M0M, and an incident electromagnetic field entering each lattice in the scatterer is determined by using the acquired current distribution. A scattering electromagnetic field from the scatterer is determined by the scattering field type FDTD method from the acquired incident electromagnetic field, and an electromotive force induced in each segment of the electromagnetic radiation wave source is determined from the acquired scattering electromagnetic field, and the current distribution is determined again in consideration of the induced electromotive force. This processing is repeated until the incident electromagnetic field to each lattice in the scatterer or the like is converged.
