Abstract Metasurfaces have attracted widespread interest owing to their ability control light at the nanoscale level. However, optical response of dipole mode-based metasurfaces is sensitive changes in resonator period and incidence angle; thus, device performance typically degrades practical applications presence non-normal incident light. Here, we study cross-shaped Mie resonators based on qu...

Abstract In this paper, we theoretically and experimentally demonstrated photothermal nonlinearities of both forward backward scattering intensities from quasi-perfect absorbing silicon-based metasurface with only ? /7 thickness. The is efficiently heated up by effect under laser irradiation, which in turn modulates the spectra via thermo-optical effect. Under a few milliwatt continuous-wave ex...

Terahertz wavefront manipulation is one of the key terahertz technologies. While few research works on has broadband and dual-polarized responses. Here a Huygens’ metasurface proposed to realize high efficient wave anomalous refraction. By constructing simultaneous electric magnetic responses in bi-layer produce resonance, large phase changes for are achieved. A change over 300° with transmissi...

One of the long-standing problems in antenna engineering is the realization of highly directive beams using low-profile devices. In this paper, we provide a solution to this problem by means of Huygens' metasurfaces (HMSs), based on the equivalence principle. This principle states that a given excitation can be transformed to a desirable aperture field by inducing suitable electric and (equival...

This paper describes a metasurface designed utilizing either a Frequency Selective Surface (FSS) that has band-pass characteristics or one with band-rejection filtering characteristics in order to clarify the relationship between the filtering characteristics of the FSS and the Perfect Magnetic Conductor (PMC) characteristics of the metasurface. The effects of the filtering characteristics of t...

We propose a single low-profile skin metasurface carpet cloak to hide objects with arbitrary shape and size under three different waves, i.e., electromagnetic (EM) waves, acoustic waves and water waves. We first present a metasurface which can control the local reflection phase of these three waves. By taking advantage of this metasurface, we then design a metasurface carpet cloak which provide...

Metasurface have recently generated much interest due to its strong manipulation of electromagnetic wave and its easy fabrication compared to bulky metamaterial. Here, we propose the design of a multi-spectral metasurface that can achieve beam deflection and broadband diffusion simultaneously at two different frequency bands. The metasurface is composed of two-layered metallic patterns backed b...
