Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Polarization-independent nonlocal metasurfaces

Optica Imaging Congress (3D, COSI, DH, FLatOptics, IS, pcAOP), 2023
We design a polarization-independent metasurface using guided resonances with degenerate band curvatures in a photonic crystal slab. Our device can perform both free-space compression and spatial differentiation when operated at different frequencies at normal incidence.

Polarization‐Independent Dispersive Complex‐Amplitude Modulation via Anisotropic Metasurfaces

Laser and Photonics Reviews
Polarization‐independent characteristic is highly desirable for practical applications, and for metasurfaces, it is typically achieved through isotropic structures.

Lactate induces tumor-associated macrophage polarization independent of mitochondrial pyruvate carrier-mediated metabolism.

International Journal of Biological Macromolecules, 2023
Tumor cell-derived lactate has been recognized as the key driver of polarization in tumor-associated macrophages (TAMs). Intratumoral lactate can be transported into macrophages to fuel the TCA cycle, which is mediated by mitochondrial pyruvate carrier ...

Ultrathin Multiband Polarization-Independent Terahertz Absorber as a Biosensor

IEEE Sensors Journal, 2023
A multiband electromagnetic terahertz (THz) absorber is proposed as a biosensor. The proposed design consists of a metallic resonator loaded with multiple ring-shaped slots, dielectric material, and a metallic ground plane.

Dispersion-Engineered, Broadband, Wide-Angle, Polarization-Independent Microwave Metamaterial Absorber

IEEE Transactions on Antennas and Propagation, 2021
In this article, by deliberately controlling multiple resistive electric and magnetic resonances in terms of dispersion and dissipation, a low-profile, wideband, microwave metamaterial absorber with wide-angle and polarization-independent responses is ...

Symmetric metasurface with dual band polarization-independent high-Q resonances governed by symmetry-protected BIC.

Optics Letters, 2021
In this Letter, we propose a symmetric metasurface composed of single-sized amorphous-silicon (a-Si) cuboids tetramer clusters that support two resonances with opposite symmetry, i.e., in-plane magnetic dipole (MD) resonance and in-plane toroidal dipole (
