Phononic crystal surface mode coupling and its use in acoustic Doppler velocimetry
(Elsevier Science Bv, 2016)
It is numerically shown that surface modes of two-dimensional phononic crystals, which are Bloch modes bound to the interface between the phononic crystal and the surrounding host, can couple back and forth between the ...
Sharp bends of phononic crystal surface modes
(Iop Publishing Ltd, 2015)
Sharp bending of surface waves at the interface of a two-dimensional phononic crystal (PnC) of steel cylinders in air and the method of using a diagonally offset cylindrical scatterer are numerically demonstrated by ...
Low-concentration liquid sensing by an acoustic Mach-Zehnder interferometer in a two-dimensional phononic crystal
(Iop Publishing Ltd, 2015)
Mach-Zehnder interferometer formed by liquid-filled linear defect waveguides in a two-dimensional phononic crystal is numerically realized for sensing low concentrations of an analyte. The waveguides in the square phononic ...
Evanescent coupling between surface and linear-defect guided modes in phononic crystals
(Iop Publishing Ltd, 2016)
Evanescent coupling between surface and linear-defect waveguide modes in a two-dimensional phononic crystal of steel cylinders in air is numerically demonstrated. When the ratio of scatterer radii to the lattice constant ...
An Acoustic Add-Drop Filter in a Phononic Crystal for High-Sensitivity Detection of Methanol in Ethanol in the Liquid Phase
(Institute of Electrical and Electronics Engineers, 2022)
An add-drop filter based on linear waveguides coupled through a ring resonator in a two-dimensional phononic crystal is introduced and its operation in detecting methanol concentration in ethanol is numerically investigated. ...
Determination of methanol concentration in ethanol in liquid phase by a phononic crystal Mach-Zehnder interferometer
(Physical Societies of the Nordic Countries, 2021)
A practical and portable ultrasonic interferometric sensor to detect methanol concentration in ethanol in the liquid phase is numerically investigated. For high-sensitivity operation, the sensor is designed as a Mach-Zehnder ...
