title = "Complex transmittance gratings based on subwavelength metallic structures",
abstract = "Subwavelength metallic structures are used to design gratings with a great variety of transmittance levels. Such gratings can answer growing needs for complex transmittance devices, particularly useful for wave-front analysis applications. Having in mind the conception of a perfectly sinusoidal transmittance for the mid-infrared, we have decided to test the ability of subwavelength lamellar gratings to code the transmittance with several levels. In order to calibrate gratings transmission, as a function of the fill factor, we have designed, realized and measured samples made of six 2mm {\texttimes} 2mm gratings, with transmittance ranging from 10\% to 95\%. Experimental results for TM- and TE-polarized light are reported and analysed.",
