title: Power losses in lamellar gratings.
abstract: Power losses in lamellar gratings per groove length are obtained by integrating the square of the tangential component of the magnetic field, obtained from the infinite conductivity solutions, along the grating profile. The groove fields for the perfectly conducting grating are generated by matching a superposition of diffracted plane waves above the grating to an exact solution of the groove boundary value problem for each polarization. Diffraction effects in the groove energy density and in the power losses are clearly evident.
