$RCWArefractiveindexreal

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

Example

$RCWArefractiveindexreal 
1       1      1   ...until the total lambda number$RCWAlamdalength
0.2     0.2    0.2
...
...
... until the total layer number $RCWAtotallayer

3.If not pressed, $RCWAlamdalength will equal 1, and the wavelength will be determined by step 4.

6.If pressed, $RCWAlamdalength will equal the value you set.

$RCWAsourcelength is no longer used.
