3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity
Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

Reconfigurable terahertz grating with enhanced transmission of TE polarized light
We demonstrate an optically reconfigurable grating with enhanced transmission of TE-polarized waves in the terahertz (THz) waveband. This kind of grating is realized by projecting a grating image onto a thin Si wafer with a digital micromirror device ...

A new type of artificial spin ice (ASI) lattices, i.e., in the ASI system embedded in the perpendicular magnetic anisotropy (PMA) matrix, is proposed. The numerical simulations reveal a strong magnon–magnon coupling between the bulk second‐order mode of the ASI and the fundamental mode of the PMA matrix, supported by a pronounced anticrossing frequency

Tailoring the plasmon-induced transparency resonances in terahertz metamaterials.
We experimentally demonstrate that a coupled metamaterial composed of sub-wavelength split-ring-resonators (SRRs) and closed-ring-resonators (CRRs) can tailor the plasmon-induced-transparency (PIT) resonances when the external electric field is parallel ...
