Extinction Index

Extinction Index = {model_name} {float} []

Description / Usage

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

CONSTANT

Name of the model for constant extinction index

• <float> -the value

TABLE

See TABLE instructions, WAVELENGTH is probably what you want to interpolate with

Examples

Following are sample cards:

Extinction Index = CONSTANT 1.
Extinction Index = TABLE 2 WAVELENGTH 0 LINEAR FILE=k.txt

Technical Discussion

This card is utilized to set the extinction index, used for acoustic and time-harmonic Maxwell.
