Brewster angle for plasmonic gratings
In this paper, we analyze the transmission properties of metallic gratings at optical frequencies. In particular, we show that an inherently ultra-broadband tunneling mechanism may be obtained based on impedance matching between the guided modes supported by ultranarrow slits and freespace TM plane waves impinging at an oblique angle. This phenomenon is the analogous of the well-known Brewster ...
متن کاملPlasmonic Micro Lens for Extraordinary Transmission of Broadband Light
Extraordinary transmittance and focusing of light in quasi far field region using miniaturized optical devices is a daunting task. A polarization independent, broadband, planar metallic transmissive micro aperture capable of achromatically focusing visible light in quasi far field region is proposed. The calculated enhancement factor of transmission efficiency was about ~2.2. The total transmis...
متن کاملLoss mechanisms in mid-infrared extraordinary optical transmission gratings.
The optical properties of periodic arrays of subwavelength apertures in metal films on GaAs substrates are studied. Specifically, geometric and material losses for these plasmonic structures are characterized using angular dependent transmission, normal incidence reflection, and angular dependent diffraction experiments, in addition to a crossed-polarizer transmission experiment. The optical pr...
متن کاملExtraordinary transmission through subwavelength dielectric gratings in the microwave range.
We address the problem of the transmission through subwavelength dielectric gratings. Following Maurel et al. [Phys. Rev. B 88, 115416 (2013)], the problem is reduced to the transmission by an homogeneous slab, either anisotropic (for transverse magnetic waves, TM) or isotropic (for transverse electric waves, TE), and an explicit expression of the transmission coefficient is derived. The optimu...
متن کاملBroadband absorbers and selective emitters based on plasmonic Brewster metasurfaces
We discuss the possibility of realizing utlrabroadband omnidirectional absorbers and angularly selective coherent thermal emitters based on properly patterned plasmonic metastructures. Instead of relying on resonant concentration effects that inherently limit the bandwidth, we base our design on the combination of two inherently nonresonant effects: plasmonic Brewster funneling and adiabatic pl...
