Electromagnetic wave analyzer and program for same

A computer program product which enables a computer to divide a given computational domain into a plurality of cells and numerically analyze transitional behavior of electromagnetic fields on an individual cell basis, the computer program product causing the computer to perform the steps of:

• (a) identifying uniformity of cells that surround each space point defined in the computational domain;
• (b) calculating electromagnetic field components at a space point with a first calculation method when the surrounding cells are identified as being uniform in size;
• (c) calculating electromagnetic field components at a space point with a second calculation method when the surrounding cells are identified as being non-uniform in size, the second calculation method having smaller computational errors than those of the first calculation method;
• and
• (d) outputting the electromagnetic field components at every space point which have been calculated in the first and second calculating steps (b) and (c).
