A comprehensive and full-featured computational physics suite for boundary-element analysis of electromagnetic scattering, fluctuation-induced phenomena (Casimir forces and radiative heat transfer), nanophotonics, RF device engineering, electrostatics, and more. Includes a core library with C++ and python APIs as well as many command-line applications.
I have been interested in angular momentum of thermal radiation especially from non-equilibrium systems and your work on torques and forces (https://arxiv.org/pdf/1708.01985.pdf) is quite helpful as a starting point. I am researching along these lines and I had a question with respect to these calculations with scuff-neq tool.
In general, for circularly polarized monochromatic light (~ E x + iE y), if we look at the spectral Maxwell Stress Tensor, the correlations are complex valued. In fact, the Stokes S_3 parameter which denotes the handedness, is proportional to imaginary part of correlations <Ex*(w) Ey(w)> which is non-zero for above circularly polarized light. In scuff-em, all the components are always real-valued and spectral tensor is symmetric. Could you tell more about the underlying symmetrization that makes it real valued ?
