We demonstrate the extensive improvement of the effective refractive index of designed
metamaterials through the coupling effect of double layers in terahertz region. It is interesting …

In order to design optical metamaterials to surpass the limitation of unnaturally high
refractive index in visible range, we propose the nanocylinders nanostructure with …

We report a polarization-independent unnaturally high refractive index metamaterial. It is
found that the effective permittivity of the designed metamaterial can be drastically increased …

Traditional metal metasurfaces have inherent non radiative losses. In this paper, an all
dielectric metasurface is proposed, which can flexibly manipulate the terahertz wave high …

Magnetic light and matter interactions are generally too weak to be detected, studied, and
applied technologically. However, if one can increase the magnetic power density of light by …

The rotation control of particles in optical tweezers is often subject to the spin or orbit angular
momentum induced optical torque, which is susceptible to the mechanical and …

To overcome the intrinsic nonradiative losses in metallic encoding metasurface, we propose
an all dielectric encoding metasurface by using cylinder microstructure. To flexibly …
