$RCWArefractiveindex
出自 DDCC TCAD TOOL Manual
The $RCWArefractiveindex command is used to define the refractive index in each region with different wavelength.
$RCWArefractiveindex
[n_{1,1} n_{1,2} n_{1,3}]-lambda1 [n_{1,1} n_{1,2} n_{1,3}]-lambda2 layer1 - Nlambda * xdiv [n_{2,1} n_{2,2} n_{2,3}]-lambda1 [n_{2,1} n_{2,2} n_{2,3}]-lambda2 layer2 - Nlambda * xdiv ... total layer
