“…2 (b)), an X-shaped pattern emerging from the excitation point is observed within the phononic crystal region. This phenomenon is known as phonon focusing or collimation [27] , [28] . When the collimated phonon beams reach the corners of the phononic crystal, they are converted to fan-shaped wave patterns in the pristine region.…”

“…We have introduced the commonly applied liquid phononic crystals sensor concept, featuring a defect. Meanwhile, several reports are available, ranging from proof-of-concept and new designs or concepts [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ], to consideration of experimental influences [ 38 , 39 ] and 3D printing [ 40 , 41 ], to the measurement of real samples [ 42 , 43 ]. Typical frequencies range from several hundred kHz to a few MHz, the respective dimensions of the phononic crystal from units of millimetres to 100 µm.…”

“…The advantage of using these devices is that any external influence of pressure, or temperature, among others, will affect both the reference and the sample. Kaya et al recently developed a theoretical study about an acoustic phononic crystal Mach–Zender interferometer with two signal paths, one for the reference and one for the sample and could be used as a temperature compensation mechanism [ 25 ].…”
