CALCULATION DEVICE AND CALCULATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18506053 titled 'CALCULATION DEVICE AND CALCULATION METHOD

The patent application describes a calculation device that divides a sample into cells and calculates the electromagnetic field of each cell based on physical property values.

The calculation portion uses Maxwell's equations to calculate the electromagnetic field of the sample and connecting portion numerically.
The connecting portion's electromagnetic field is Fourier transformed into a plane wave expressed by a wavenumber vector.
The transformed plane wave is set as an initial value and used to calculate the wavenumber space electromagnetic field analytically using Helmholtz's equation.
The electromagnetic field of the analytic solution applying portion is calculated by inverse Fourier-transforming the wavenumber space electromagnetic field.

Original Abstract Submitted

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.
