Metasurface-based structural color with high resolution is promising for printing and encryption. However, achieving tunable colors in practical applications challenging owing to the immutability after fabrication of metasurfaces. Herein, we proposed polarization-switchable dielectric metasurfaces full colors. The colorful images can be switched on/off by controlling polarization incident light. For nanorods metasurfaces, all turned black "off" mode because near-zero reflection, uniform was...
Plasmonic sensing based on nanostructures is a powerful analytical tool for ultrasensitive label-free biomolecule detection that holds great potential in the field of clinical diagnostics and biomedical research. Here, we report fabrication, characterization, principle operation gold nanorod hyperbolic metamaterials (NHMMs) along with bulk refractive index biomolecular detection.

Absorptivity higher than 90% normal incidence is supported over wide wavelength range from 300 2215 nm, due the change isofrequency surface (IFS). The operating...
Metallic plasmonic nanosensors that are ultra-sensitive, label-free, and operate in real time hold great promise the field of chemical biological research. Conventionally, design these nanostructures has strongly relied on time-consuming electromagnetic simulations iteratively solve Maxwell's equations to scan multi-dimensional parameter space until desired sensing performance is attained. Here, we propose an algorithm based particle swarm optimization (PSO), which combination with a machine...

A near-ideal solar absorber, which is composed of a metal nanowire array and planar multilayer system, proposed investigated. Both numerical analytical results show that the nanostructure can achieve over 90% optical absorption throughout wavelength range 300–1909 nm due to coupled effect multiple resonance modes, maintain good stability wide incident angle regardless polarization states. Meanwhile, for practical applications, total photothermal conversion efficiency reach 95.57% at...

An ultra-narrow angular optical transparency window based on photonic topological transition (PTT) is theoretically and numerically investigated in a low-loss hyperbolic metamaterial (HMM) platform, which consists of aligned metallic nanowires embedded indielectric host matrices. Our results indicate that, near the point PTT, designed system exhibits high-efficiency selectivity close to normal incidence by tailoring topology metamaterial's equi-frequency surface (EFS). Moreover, operating...
Metasurfaces with the capability of spectrum manipulation at subwavelength can generate structural colors. However, their practical applications in dynamic displays are limited because optical performance is immutable after fabrication metasurfaces.

We investigate potencial these metasurfaces by...

A sensor based on plasmon-waveguide resonance (PWR) exhibits an impressive narrow linewidth and has attracted extensive attention in plasmon label-free sensing. However, the low surface electric field intensity limits detection ability of biomolecules, where refractive index changes are restricted at surface.
