I designed double slit experiment on COMSOL using RF module and applied "Scattering boundary condition" in-front of slits to have interference pattern here. Is it suitable? If not, then how can I get interference pattern.
In one paper, I saw it to be about 36%. But as the paper was published in 1997, shouldn't modern household gas stoves be more efficient?
