Complex-Eigenfrequency Band Structure of Viscoelastic Phononic Crystals
Applied Sciences, 2019 The consideration of material losses in phononic crystals leads naturally to the introduction of complex valued eigenwavevectors or eigenfrequencies representing the attenuation of elastic waves in space or in time, respectively.

Tunable guided waves in a soft phononic crystal with a line defect
APL Materials, 2021 Defects in phononic crystals may induce localized states and therefore can serve as microcavities, waveguides, or perfect mirrors. In this article, we numerically and experimentally investigate the deformation behavior and wave propagation ...

Chip‐Scale Terahertz Sensing Driven by Supercoupling Induced Transparency in Topological Cavities
Laser &Photonics Reviews, EarlyView.Supercoupling‐induced transparency (SIT) in topological cavities enables sensitive terahertz sensing on a chip. Strong field confinement and slow light response enhance interactions with thin films, enabling thickness detection through resonance shifts and group delay changes.
