Multiband High- Q Terahertz Resonances in a Twisted Triangular Moire Metasurface

Abstract Bound states in the continuum (BICs) are nonradiative modes embedded within the continuous spectrum of propagating states that remain perfectly localized without leaking into radiation channels. Symmetry-protected BICs (SP-BICs) are induced by structural symmetry at the...

Screening colorectal tumor-associated fibroblasts using dual-channel THz biosensor

In clinical oncology, label-free identification of colorectal tumor-associated fibroblast (CAF) subtypes is challenging. In this work, a terahertz (THz) metasurface exhibiting dual channels of probation, quasi-bound states in the continuum (q-BICs) and electromagnetically induced...
