Reply To: Reflection and transmission values do not add up to 1

Hi Lucio,

If the source is injected in the +x/y/z direction, then the transmission will be positive and reflection will be negative by convention.

So, when you add up the transmission and reflection make sure you use T - R (where R will be negative by convention).

If it is along the -x/y/z directions, use -T + R (where T will be neagtive by convention).

 

That being said, I would still expect gold to have a finite amount of absorption at 1550 nm. So, I would expect the sum of transmission and reflection to be less than 1. I will recommend performing convergence testing to confirm the validity of the results, especially if you think they are unreasonable at the moment.
