Independent control of dispersion band and linewidth of guided-mode resonances by using dual-ridge unit-cell structures

초록

We present a dual-ridge unit cell enabling deterministic, independent tuning of guided-mode resonance frequency and linewidth. A closed-form parametric search space maps geometry to spectral metrics, removing trial-and-error. The framework supports multi-metric design and uncovers emergent non-Hermitian and topological features, including exceptional points and Fermi arcs.
