Abstract:
We present a theorical investigation of the optical transmission of a dielectric grating carved in a tungsten layer. For appropriate wavelengths tungsten indeed shows a dielectric behavior. Our numerical simulation leads to theoretical results similar to those found with metallic systems studied in earlier work. The interpretation of our results rests on the idea that the transmission is correlated with the resonant response of eigenmodes coupled to evanescent diffraction orders.
