The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

Herein, we establish a hybrid coupling model (HCM) containing both near-and far-field
couplings to describe the electromagnetic response of the coupled-grating system …

Extreme confinement of incident acoustic waves remains challenging due to the conflict
between reflection elimination and weak dissipation. In this study, by realizing a Friedrich …

Near-field coupling is a fundamental physical effect, which plays an important role in the
establishment of classical analog of electromagnetically induced transparency (EIT) …

We study theoretically and experimentally the acoustic Purcell effect induced by quasi-
bound states in the continuum (quasiBICs). A theoretical framework describing the acoustic …

Timbre, as one of the essential elements of sound, plays an important role in determining
sound properties, whereas its manipulation has been remaining challenging for passive …

Artificially structured metamaterials with metallic or dielectric inclusions are extensively
studied for exotic light manipulations via controlling the local‐resonant modes in the …
