Hello!
I have a question need your help. I calculate a grating model in comsol4.3, and is illuminated at normal incidence with a TM-polarized plane wave. There question is how can I get the distribution of the reflected field? Generally, field intensity distribution contains both incident wave and reflected wave after simulation. How can I get the field distribution after the incident wave is subtracted. For example, if I want get the H-field intensity distribution of reflect wave , How to do it?
