ELECTROMAGNETIC FIELD SIMULATOR, ELECTROMAGNETIC FIELD ANALYZER, ELECTROMAGNETIC FIELD SIMULATION PROGRAM, AND ELECTROMAGNETIC FIELD ANALYSIS PROGRAM

摘要

PPROBLEM TO BE SOLVED: To analyze an electromagnetic field by means of small storage capacity and short-time processing by using an electromagnetic simulator that repeats the use of electromagnetic field spatial distribution at a time point to calculate electromagnetic field spatial distribution at a subsequent time point. PSOLUTION: This electromagnetic field analyzer is characterized by being equipped with a multiplication/cumulation part and an amplitude/phase calculation part. On at least one vector of an electric field vector and a magnetic field vector in an electromagnetic field, each time the spatial distribution of the electromagnetic field is calculated over one cycle or more of a trigonometric function expressing the vibration of a prescribed frequency, the multiplication/cumulation part multiplies the value of the trigonometric function by the vector to cumulatively adding up the results of the multiplication over one cycle or more of the trigonometric function. The amplitude/phase calculation part calculates an amplitude and phase by using the result of the cumulative addition by the multiplication/cumulation part on an electromagnetic wave of the same frequency as the above frequency.
