Study of scattering from a periodic grating structure using Lorentz-Drude model and Chandezon method

Presented study deals with the scattering from a dispersive, lossy and periodic grating structure using differential formalism of the Chandezon method also known as C-method. Losses and dispersion in the grating structure has been introduced through Lorentz-Drude model. For transverse magnetic and transverse electric excitation, efficiency behaviour of the diffracted orders in the optical regime has been analyzed and discussed.
