  journal={arXiv: Optics},
A multi-reflection model of grating diffraction based on the simplified modal method is proposed. Simulation results for a guided mode resonance Brewster grating using our method and rigorous coupled wave analysis are presented to verify our model. The solution of our method is in good agreement with that of rigorous coupled wave analysis. Benefiting from its clear physical view, this model helps us to better understand the diffraction process inside subwavelength gratings. On the basis of the…

Highly improved convergence of the coupled-wave method for TM polarization
The coupled-wave method formulated by Moharam and Gaylord [ J. Opt. Soc. Am.73, 451 ( 1983)] is known to be slowly converging, especially for TM polarization of metallic lamellar gratings. The slow
Unified design of sinusoidal-groove fused-silica grating.
The performance of the sinusoidal grating is better than a conventional rectangular one, which could be useful for practical applications and could be used as the design guidelines for wavelength-independent structure from deep ultraviolet to far infrared.
