“…Moreover, due to the complex structure of the meta-materials/meta-surfaces and the fabrication difficulty, they are not suitable for practical applications. Previously, we proposed a theoretical model to investigate the anomalous reflection of ultra-thin metallic nano-strips, the simulation shows a reasonable agreements with the corresponding experimental results, 19 and the phase modulation was also analyzed. 10 Considering that the ultra-thin metallic nano-strips is transparent for visible light, this article puts forward an idea of ultra-thin metallic nano-strips based polarization converter which has a function of traditional quarter-wave plate.…”

Ultra-thin metallic nano-strips (thinner than skin depth) can lead to anomalous reflection for a transverse magnetic (TM) incidence of some wave-lengths, due to the phase modulation of localized surface plasmon resonance. Based on the principle above, we proposed a method of polarization modulation using ultra-thin metallic nano-strips. When irradiating nano-strips vertically by light with a given polarized angle, we can utilize the phase difference of the TM transmission and transverse electric (TE) transmission near anomalous reflection region to modulate transmission polarization. We have designed and fabricated the ultra-thin metallic nano-strips with the function of quarter-wave plate, the attained transmission Stokes parameter S3 is 0.95. The nano-strips is easy to design and fabricate, also compatible with other optics devices, hence has the potential applications in integrated optics field.

The solution of large matrix eigenvalues and complex linear equations limits the Fourier modal method (FMM) application in ultrathin metallic gratings (UMG) analysis. This paper proposes an efficient and explicit FMM method for analyzing UMG. The proposed method avoids solving complex linear equations and eigenvalues of eigenmatrix in the conventional method by simplifying the implementation equations. Two numerical examples then verify the reliability of the proposed method compared with CST simulations and the conventional method. The proposed method is proven efficient in decreasing the CPU time by over 80% and demanding significantly less memory.

“…They often have optical properties different from the same bulk material. Partial transparency and conductivity allow using them as electrodes for solar cells [1] and other optoelectronic devices [2,3]. Thin metal films are widely used in optical instrumentation (mirrors, beam splitters, different specific coatings and so on).…”

Angular ellipsometric measurements of thin Ag, Cu films covered by HfO 2 protective layer were performed. The ellipsometric parameters ψ and ∆ were measured in θ = 43°…85° light incidence angle range, where ψ is the azimuth of restored linear polarization, ∆ is the phase shift between p-and s-components of reflected light. For comparison, thin Au film (traditional sensor for surface plasmon resonance (SPR)) was examined as well. The curve ∆(θ) for all the samples investigated falls down with increasing angle of light incidence, while ψ(θ) changes relatively weakly. It has been ascertained that the increase in the thickness of HfO 2 layer affects the tan(ψ) value, while tan(ψ) deviation is mainly determined by the type of metallic film. With the growth of HfO 2 layer, the minimum position of tan(ψ) shifts to smaller angles. From these angular dependences, one could choose the appropriate SPR-compatible structure due to maximal deviation of tan(ψ). To optimize layer thickness for a high SPR-response, spectral measurements and additional calculations are required.
