Metamaterials are artificially-engineered materials, possessing properties which are not
readily observable in materials existing in nature. Since they show very novel properties …

The existing theories which aim to explain the extraordinary optical transmission of a
metallic film pierced by a two-dimensional subwavelength hole array [TW Ebbesen, HJ …

Numerical evidence is presented that shows that, for metallic lamellar gratings in TM
polarization, the coupled-wave method formulated by Moharam and Gaylord [J. Opt. Soc …

It is theoretically shown that nanometric silver lamellar gratings present very strong visible
light absorption inside the grooves, leading to electric field enhancement of several orders of …

We present an experimental and theoretical study of the optical properties of metal-dielectric-
metal structures with patterned top metallic surfaces, in the THz frequency range. When the …

An efficient numerical method for accurately determining the real and/or complex
propagation constants of guided modes and leaky waves in general multilayer waveguides …

We discuss examples of designs for all-dielectric reflection gratings that tolerate high
intensity and are potentially capable of placing up to 99% of the incident light into a single …

Since the 80's, specialists of gratings can rely on very powerful grating softwares [1-6].
These softwares are able to compute grating efficiencies for almost any kind of grating in any …

A rigorous modal analysis of lamellar gratings, ie gratings having rectangular grooves, in
conical mountings is presented. It is an extension of the analysis of Botten et al. which …

The design and fabrication of large-area, high-efficiency metallic gratings for use in high-
power laser systems is described. The gratings exhibit a diffraction efficiency in excess of …
