Abstract

Reconfigurable Quasi-BIC Terahertz Metasurfaces The cover image depicts a MEMS-enabled bimaterial cantilever metasurface supporting reconfigurable terahertz quasi–bound states in the continuum (quasi-BICs) via controlled symmetry breaking. In-plane mirror symmetry is broken through lateral resonator asymmetry, while MEMS-actuated cantilever tilting introduces dynamic out-of-plane asymmetry. Together, these mechanisms enable independent control of radiative and intrinsic losses, allowing active tuning of resonance linewidth and quality factor. More details can be found in the Research Article by Richard D. Averitt, Xin Zhang, and co-workers (DOI: 10.1002/adom.202503164).
