Non-helical (e.g. bifilar or meander) resonators in shielded cavities can reduce stray coupling and support high-Q modes that are attractive substrates for adiabatic or logically reversible manipulati...

Bridge Bound states in the continuum (BIC) theory explains ultra-high-Q dielectric metasurface resonances and their sensitivity to fabrication disorder.

Symmetry-protected and accidental BIC concepts predict when radiative channels decouple, creating quasi-BIC resonances with very high quality factors in dielectric metasurfaces. This bridges scatterin...

Bridge Metamaterials engineered near an epsilon-near-zero (ENZ) permittivity crossover concentrate electromagnetic fields and reshape resonance quality factors because dispersion-dominated response modifies radiative and absorptive loss partitioning — nanophotonics ↔ cavity Q engineering distinct from helical chiral designs.
