Split-ring resonator (SRR), one kind of building block of metamaterials, has attracted wide attentions due to the resonance excitation of electric and magnetic dipolar response. Fundamental plasmon properties and potential applications in novel three dimensional vertical split-ring resonators (VSRRs) are designed and investigated. The resonant properties arose from the electric and magnetic interactions...
In the past decade, a number of interesting designs have been proposed to generate artificial magnetism at optical frequencies using plasmonic metamaterials, but owing to the planar configurations of typically fabricated metamaterials, the magnetic response is mainly driven by the incident electric field. Here, we fabricated vertical split-ring resonators (VSRRs) which behave as magnetic metamolecules...
We present vertical split-ring resonators (VSRRs) which behave as magnetic metamolecules sensitive to both the incident electric and magnetic fields upon excitation. A couple of potential applications such as VSRR-based highly sensitive refractive-index sensor and metasurface for light manipulation in optical communication frequency will also be demonstrated.
Holograms are the optical devices to reconstruct images by recovering amplitude and phase of light, which show many applications in our daily life. Recently, the metasurfaces, an array of sub-wavelength antenna, show the abilities to manipulate both the amplitude and phase of incident electromagnetic wave in a wide electromagnetic region from visible to microwave frequencies. Here, we realized a high-efficiency...
We report a coupling mode transition from pure plasmon coupling to plasmon-microcavity hybridization in THz using liquid metal whose shape can be tuned, not only from disk to droplet, but also from 2D to 3D.
A plasmonic liquid-liquid (PLL) waveguide using Au nano-particles (NPs) colloidal solution is configured on a micro-optical-fluidic system (Mmicro-optical-fluidic system (MOFSOFS) chip for interest extensions of surface plasmon resonance (SPR) assisted measurements. For characterizing the PLL waveguide, the propagating modes are studied with the scattering images and the measurement of transmission...
