摘要

The dielectric dispersion characteristic model device on base dispersion characteristic composite curve accessory dielectric date is temporarily dielectric frequency and frequency, the complex dielectric permittivity measured according to the unit recipient before processing according to an embodiment of the present invention using a complex fraction function balance type time domain electromagnetic numerical analysis; The function of frequency for frequency indicates entry into a real part and an imaginary part, and including multiple coefficients a Function Generation unit utilizes complex fraction function formula (QCRF), is used to generate a dispersion feature functionality, represents the characteristic distributions of complex dielectric permittivity; By the transformation matrices dispersion for dispersion property function for calculating each coefficient complex fraction an of function expression, dispersion characteristic modeling is executed by the coefficient of the difference of computation in complex fraction function formula for the numerical analysis that characteristic includes dielectric time domain electromagnetic of modeling.
