Abstract: A calculation device includes a calculation portion that divides a sample having a numerical solution applying portion, a connecting portion and an analytic solution applying portion into a plurality of cells, and calculates an electromagnetic field of each cell based on a physical property value associated with the cell. The calculation portion calculates the electromagnetic field of the numerical solution applying portion and the connecting portion by a numerical calculation using Maxwell's equations, Fourier transforms the calculated electromagnetic field of the connecting portion into a plane wave expressed by a wavenumber vector, sets the transformed plane wave as an initial value, calculates the a wavenumber space electromagnetic field by an analytic solution of Helmholtz's equation, when the plane wave propagates the analytic solution applying portion in the propagation direction, and calculates the electromagnetic field of the analytic solution applying portion by inverse Fourier-transforming the wavenumber space electromagnetic field.
