ELECTROMAGNETIC FIELD SIMULATION METHOD. ELECTROMAGNETIC FIELD SIMULATION PROGRAM, AND COMPUTER READABLE RECORDING MEDIUM RECORDED WITH THE PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic field simulation method capable of simulating an electromagnetic field of a highly accurate TM mode in a two-dimensional plane where a dielectric constant consists of two media that discontinuously change and to provide an electromagnetic field simulation program and a computer readable recording medium recorded with the program. SOLUTION: When the two media with different dielectric constants are in contact with each other with one straight line as a boundary in a plane and an electromagnetic field composed of the TM mode exists, a plane where three types of lattice points with different electromagnetic field that are allocated to one another are arranged at equal intervals and digitized is constructed as a virtual plane equivalent to the plane. Dielectric constants satisfying a prescribed relational expression are respectively given to a lattice point located near the boundary among the lattice points to which electrical field components are allocated, to calculate a change in an electromagnetic field corresponding to digitized time change.
