Permittivity and Displacement current in WhitneyAVHarmonicSolver
Posted: 06 Mar 2021, 03:24
Dear all,
Can I have your thoughts on dielectric material in WhitneyAVHarmonicSolver?
I'm trying to analyze electromagnetic harmonic field with a slightly conductive part and a dielectric part.
Since the conductive part is anisotropic, I think WhitneyAVHarmonicSolver is the best for analysis.
But I should find the way to take permittivity in the analysis, since permittivity is neglected in this solver.
From time-harmonic Maxwell's equations,
curl H = sigma E + i epsilon omega E = (sigma + i epsilon omega) E
i: imaginary unit
omega: frequency
epsilon: permittivity
sigma: conductivity
So I think I can set "sigma" to real part of conductivity of conductive material, and "epsilon omega" to imaginary part of conductivity of dielectric material.
Do you think this assumption has problems?
