Ultra-thin wide-band split-ring resonator-based compact mu-negative metamaterial for terahertz applications

Results in Engineering
This paper focuses on designing and investigating a new type of metamaterial called an ultra-thin wide-band mu-negative (MNG) metamaterial. The targeted frequency range is 0.1–10 THz.

Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

Advanced Photonics Research, EarlyView.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Diffractive Synthesis of Multipole Interference States Using Low‐Index Mesoscale Dielectric Structures

Advanced Photonics Research, EarlyView.
Multipole interference (MPI) plays pivotal roles in electromagnetics. In optics, it has been realized typically with the Mie resonance in high‐index, deep‐subwavelength‐scale dielectric resonators. A new, diffraction‐based MPI scheme is proposed and demonstrated with low‐index, mesoscale dielectric structures.

Tuning the buckling sequences of metamaterials using plasticity [PDF]

arXiv
Material nonlinearities such as hyperelasticity, viscoelasticity, and plasticity have recently emerged as design paradigms for metamaterials based on buckling. These metamaterials exhibit properties such as shape morphing, transition waves, and sequential deformation.

Investigating the Potential for Label‐Free Detection of Cell Apoptosis through Terahertz Nano‐Metasurfaces

Advanced Photonics Research, EarlyView.
This study demonstrates a label‐free optical method to monitor cells using a terahertz metasurface‐based biosensing platform. The obtained terahertz signal change for the cell‐contained nanoslots before and after external stimulus is analyzed in terms of transmittance and frequency shift, dynamically representing the cell apoptosis process.
