Examples:

Nearfield Simulation

Nearfield of a binary trench etched into dielectric or metallic substrate: nearfield_bin_fem_vs_rcwa.pdf The simulations show a comparison of the nearfield scattered by a binary trench between Unigit RCWA and FEM. We are very grateful to Mr. Tobias Pahl from University Kassel/Germany (Lehrstuhl für Messtechnik (LMT), Fachbereich Elektrotechnik/Informatik) for kindly providing the FEM simulations.

Nearfield of a dielectric or metallic sphere (2D): nearfield_sphere_fem_vs_rcwa.pdf The simulations show a comparison of the nearfield scattered by a sphere between Unigit RCWA and FEM. We are very grateful to Mr. Tobias Pahl from University Kassel/Germany (Lehrstuhl für Messtechnik (LMT), Fachbereich Elektrotechnik/Informatik) for kindly providing the FEM simulations.
