文摘

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.
