Electrical Permittivity#

Electrical Permittivity = {model_name} {float} []

Description / Usage#

This required card is used to specify the model for electrical permittivity. Definitions of the input parameters are as follows:

CONSTANT
Name of the model for constant electrical permittivity. |

  • <float> -the value of electrical permittivity. |

COMPLEX_CONSTANT
complex permittivity (for Time-Harmonic Maxwell with Nedelec elements)

  • <float1> real part

  • <float2> imaginary part

REFRACTIVE_INDEX

Calculate permittivity using the refractive index and extinction index cards (for Time-Harmonic Maxwell with Nedelec elements) .. math:

\epsilon_r = (n - ik)^2

Where \(n\) is the refractive index and \(k\) is the extinction index

Examples#

Following are sample cards:

Electrical Permittivity = CONSTANT 1.

Technical Discussion#

This card is utilized to set the electrical permittivity for electrostatic problems.
