Orientation sensors require the monitoring of polarization-dependent surface plasmons of single nanoparticles. Herein, we present both the longitudinal and transverse surface plasmonic resonance from a single gold nanorod (AuNR) using conventional dark-field microscopy. The relative peak intensities of the transverse and longitudinal surface plasmons of a single AuNR can be successfully tuned b...

Plasmonic color generation utilizing ultrathin metasurfaces as well metallic nanoparticles holds a great promise for wide range of applications including displays, data storage, and information encryption due to its high spatial resolution mechanical/chemical stability. Most the recently demonstrated systems generate static colors; however, more advanced such storage require fast flexible means...

Microvillar photoreceptors are intrinsically capable of detecting the orientation of e-vector of linearly polarized light. They provide most invertebrates with an additional sensory channel to detect important features of their visual environment. However, polarization sensitivity (PS) of photoreceptors may lead to the detection of polarization-induced false colors and intensity contrasts. Most...

Both temperature-responsive and patterned photonic coatings are receiving a lot of attention from fundamental application point view. However, the fabrication multicolor patterns, which also temperature-responsive, remains challenging. The current work presents thermochromic coating with light polarization-dependent multiple structural colors polymer-stabilized cholesteric liquid crystal siloxa...

Context. Reflected light from giant planets is polarized by scattering, offering the possibility of investigating atmospheric properties with polarimetry. Polarimetric measurements are available for the atmospheres of solar system planets, and instruments are being developed to detect and study the polarimetric properties of extrasolar planets. Aims. We investigate the intensity and polarizatio...

A recently developed color printing system on glass plates, based on dot-by-dot laser irradiation generating the growth of metallic nanoparticles in a special coating, produces structural colors depending strongly on the illumination and observation configuration. The difficulty for an exhaustive color characterization of the printing technology comes not only from the goniochromaticity of the ...

in this paper we will prove that if $l$ is a continuous symmetric n-linear form on a hilbert spaceand $widehat{l}$ is the associated continuous n-homogeneous polynomial, then $||l||=||widehat{l}||$.for the proof we are using a classical generalized  inequality due to s. bernstein for entire functions of exponential type. furthermore we study the case that if x is a banach space then we have tha...

Optical broad-band polarimetry is presented for near-infrared color-selected active galactic nuclei (AGN) classified as quasi-stellar objects (QSOs) based on their Ks-band luminosity. More than 10% of a sample of 70 QSOs discovered in the Two Micron All Sky Survey (2MASS) with J −Ks > 2 and MKs < −23 show high broad-band linear polarization (P > 3%), and values range to a maximum of P ∼ 11%. Hi...

We present high spatial resolution (0.3) polarimetric images in the H and K bands and direct images in the L and M ′ bands of the NGC 6334 V infrared nebulae. The images show complex structures including the multi-shells and various knots in the nebulae. The appearances and colors of the eastern and western nebulae differ considerably. Our polarization images also show differences between the i...
