Heat absorption over a volume instead of an area?
I am very pleased to have discovered the heat absorption module, which calculates the absorption over an area by using the expression
0.5 Re( J*E) = 0.5 sigma |E|^2
as outlined in chapter 6.4 in the technical background. My question is: Can this be used over a volume, in order to measure the absorption within a portion of a waveguide? Alternatively, is it possible to somehow extract the field information over a volume and calculate the absorption manually?
