Electric Dispersion

You can specify the electric dispersion by providing the dependency of the real part of the electrical permittivity and of the loss tangent on the electric field frequency.

You can define orthotropic electric dispersion by specifying the components of the ϵ R and tan ⁡   δ tensors in the X, Y, and Z directions.

Isotropic

Input Data Description
EpsilonR Real part of the electrical dispersion, ϵ R .
Tan Delta Loss tangent, tan ⁡   δ .
Frequency (Hz) The frequency in Hz for each pair of electrical dispersion and loss tangent values that you specify.

Orthotropic
