2.7    Dielectric Dispersive Anisotropic

Dielectric dispersive anisotropic is a dispersive anisotropic dielectric medium with a complex relative permittivity given by Debye dispersion model with the user-specified parameters:

Debye:            e_r(w) = eps_inf  + (eps_s - eps_inf) / (1 + j w tau)

eps_inf   [dimensionless] - relative permittivity at infinite frequency,

eps_s [dimensionless] - static relative permittivity,

tau [ns] - relaxation time,

Mu = m_r [dimensionless] – relative magnetic permeability,

Sigma = s [S/m] - electric conductivity,

and

SigmaM = s_m/(k)⁴ [W/m] - magnetic loss

can be defined in each of three directions.

For particular direction, eps_s < eps_inf is not allowed, and eps_s = eps_inf causes that the medium is considered as dielectric isotropic with frequency-independent permittivity eps_inf and conductivity Sigma.

For particular direction, tau=0 causes that the medium is considered as dielectric isotropic with frequency-independent permittivity eps_s and conductivity Sigma.
