Evanescent coupling between surface and linear-defect guided modes in phononic crystals
Çiçek, Ahmet; Salman, Aysevil; Kaya, Olgun Adem; Ulug, Bülent (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 ... -
Low-concentration liquid sensing by an acoustic Mach-Zehnder interferometer in a two-dimensional phononic crystal
Salman, Aysevil; Kaya, Olgun Adem; Çiçek, Ahmet; Uluğ, Bülent (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 ... -
Phononic crystal surface mode coupling and its use in acoustic Doppler velocimetry
Çiçek, Ahmet; Salman, Aysevil; Kaya, Olgun Adem; Uluğ, Bülent (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
Çiçek, Ahmet; Salman, Aysevil; Kaya, Olgun Adem; Uluğ, Bülent (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 ...
