$RCWAabsorption2

$RCWAabsorption2 required setting tag the image refractive index. This number needs to be set in the beginning of input file. It relates to $RCWAlamdalength and $RCWAtotallayer.

Example

$RCWAabsorption2 
0       0      0   ...until the total lamda number$RCWAlamdalength
0.01    0.01   0.01

3.If not pressed, $RCWAlamdalength will equal 1, and the wavelength will be determined by step 4.
$RCWAabsorption2 will show step 5 at specified wavelength.

6.If pressed, $RCWAlamdalength will equal the value you set.
$RCWAabsorption2 will show step 7 at specified wavelengths.

$RCWAsourcelength is no longer used.
