“…The dielectric function was derived from the Drude model and should be complemented with material data of Johnson and Christy [20] if higher frequencies are of interest. We used the plasma frequency ω p = 1.37 × 10 16 rad/s and the scattering frequency ν = 8.5 × 10 13 rad/s [21] for deriving the dispersion of Ag. Both the single and double meander structure are placed in vacuum although another permittivity configuration can be easily obtained.…”

“…It was found that with certain meander geometries, plasmon resonances induce a hightransmission pass band, which is bounded by two Fano-type resonances ( Fig. 2(a)) [21,29]. This high-transmission pass band is the main reason for using meander structures for the proposed depolarizer.…”

“…When p-polarized light is incident onto a thin meander structure, two kinds of surface plasmon polaritons (SPP) are excited at the metal-dielectric interfaces, namely short range surface plasmon polaritons (SRSPP) and long range surface plasmon polaritons (LRSPP) [21]. The SRSPP represents the symmetric and low-frequency mode whereas the LRSPP corresponds to the antisymmetric and high-frequency case.…”

“…The SRSPP represents the symmetric and low-frequency mode whereas the LRSPP corresponds to the antisymmetric and high-frequency case. They can be identified by their respective field distributions [21,26] or by varying the thickness of the metal film [27,28]. It was found that with certain meander geometries, plasmon resonances induce a hightransmission pass band, which is bounded by two Fano-type resonances ( Fig.…”

Due to plasmonic excitations, metallic meander structures exhibit an extraordinarily high transmission within a well-defined pass band. Within this frequency range, they behave like almost ideal linear polarizers, can induce large phase retardation between s-and p-polarized light and show a high polarization conversion efficiency. Due to these properties, meander structures can interact very effectively with polarized light. In this report, we suggest a novel polarization scrambler design using spatially distributed metallic meander structures with random angular orientations. The whole device has an optical response averaged over all pixel orientations within the incident beam diameter. We characterize the depolarizing properties of the suggested polarization scrambler with the Mueller matrix and investigate both single layer and stacked meander structures at different frequencies. The presented polarization scrambler can be flexibly designed to work at any wavelength in the visible range with a bandwidth of up to 100 THz. With our preliminary design, we achieve depolarization rates larger than 50% for arbitrarily polarized monochromatic and narrow-band light. Circularly polarized light could be depolarized by up to 95% at 600 THz.

“…The most promising method for spectral selection when the source is white or polychromatic light is the use of plasmonic effects in metal-dielectric thin films [7][8]. This enables the creation of broadband and narrow band spectral filters with adjustable bandwidth by changing the angle of incidence of the input light.…”

Abstract. A combination of holographic and diffractive optical elements (HOE-DOEs) for multicolor signs-symbolic information display system, screens and indicators is described. These elements combine the functions of high-efficiency four-level diffractive optical elements with spectral plasmon filters having a variable bandwidth dependent on the angle of incidence. The main parameters of such HOE-DOEs were determined using the Fourier modes method. The theoretical results show that a four-level diffraction grating and a plasmon filter can be combined based on their spectral-angular characteristics, opening up the possibility for their use in display systems. IntroductionCurrently, one of the most promising practical applications of flat optics is the development of holographic and diffractive optical elements (HOE-DOEs) with binary and multi-level surface relief, as well as their integration into optical devices. HOE-DOEs with light guide substrates are used in miniature display systems [1][2][3][4][5][6]. With these combined elements, the weight and size of display and visualization systems can be significantly reduced [3,4], which allows for their use in new applications, especially in automotive and aviation systems [2,4,5], where the display is superimposed on real world imagery.The use of holographic indicators in different climatic conditions requires the selection of special photosensitive materials for HOE-DOEs. These elements may need to be physically protected or recorded directly into the glass [4]. There is a significant problem with the low diffraction efficiency of these devices [1][2][3]. Improved efficiency would allow for the use of less powerful illumination source including the possibility of using OLED-displays. In order to project multi-colored images, HOE-DOEs need to be designed with the specified spectral and angular selectivity. The development of a new type of combined HOE-DOEs with increased diffraction efficiency and spectral-angular selectivity for different photosensitive materials and glass will facilitate the development of a new generation of signs-symbolic information displays, based on holographic optical elements and light guide substrates.

It′s so easy: The readily available and highly water‐soluble [IrCl(Hedta)]Na complex is an efficient and robust catalyst for water oxidation to molecular oxygen. The reaction is driven by the reduction of Ce4+ to Ce3+. Its performances (TOF=6.8 min−1 and TON>12 000) are derived by UV/Vis spectroscopic, volumetric and electrochemical measurements, and compare favorably with those of the best catalysts reported so far.
