Why is sometimes the box monitor value greater than 1 when using a TFSF source, for example in a Mie scattering like simulation?


#1

When I use a box monitor to find the scattered fields and absorption fields along with a TFSF source,
the T value is sometimes greater than 1. Interestingly, the T value varies with the size of the source.
Why is that?


Convergence problem in FDTD
negative reflectance???

This sounds like the issue described on this page. If this is the case, the way to solve this problem is to re-normalize the transmission to the sourceintensity instead. Like this analysis group in the Mie scattering example.
