METHOD FOR ANALYZING ELECTROMAGNETIC FIELD USING FDTD METHOD, METHOD FOR REPRESENTING MEDIUM IN ANALYSIS OF ELECTROMAGNETIC FIELD, SIMULATION SYSTEM, AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a versatile technology for analyzing an electromagnetic field surely with high accuracy by representing an object being analyzed (medium) existing in an analytic space more accurately at all times. PSOLUTION: A conductor is represented by a line and the face of a cell having a side intersecting that conductor is divided by that conductor. The divided face including a position for determining the magnetic field strength is handled as one face as usual and the divided face not including that position is added to the adjacent face. Two electric field strengths are defined on the side intersecting the conductor. Magnetic field strength of a face BCDE is thereby determined using an integration path ABCDEFA and magnetic field strength of a face BEGH is determined using an integration path AFGHA.
