We reveal that finite-size solid acoustic resonators can support genuine bound states in the
continuum (BICs) completely localized inside the resonator. The developed theory provides …

Abstract In 1985 Fridriech and Wintgen proposed a mechanism for bound states in the
continuum based on full destructive interference of two resonances which can be easily …

Detecting of the levels of greenhouse gases in the air with high precision and low cost is a
very urgent demand for environmental protection. Phononic crystals (PnCs) represent a …

Ultra-sensitive greenhouse gas sensors for CO2, N2O, and CH4 gases based on Fano
resonance modes have been observed through periodic and quasi-periodic phononic …

Phononic crystals (PnCs) emerge as an innovative sensor technology, especially for high-
performance sensing applications. This study strives to advance this field by develo** new …

We propose a tunable four-channel acoustic demultiplexer, based on a fork-shaped
phononic crystal (PnC) structure, having four output ports. A square lattice of cylindrical …

In this work we study the localization of flexural waves in highly symmetric clusters of
scatterers. It is shown that when the scatterers are placed regularly in the perimeter of a …

The design of devices based on acoustic or optical fields requires the fabrication of cavities
and structures capable of efficiently trap** these waves. A special type of cavity can be …

A photonic crystal microcavity with a tunable quality factor (Q factor) has been implemented
on the basis of a bound state in the continuum using the advanced liquid crystal cell …

We propose a simple solid–liquid–solid triple layer biosensor platform based on bound
states in the continuum (BICs) and Fano resonances to detect the acoustic properties of …
