Frequency-dependence of the acoustic rectifying efficiency of an acoustic diode model

Abstract

Polariton-based band gap and generation of surface acoustic waves in acoustic superlattice lithium niobate

Asymmetric first order shear horizontal guided waves propagation in a tapered plate

“…The first realization of "acoustic diode" by Liang et al [8][9][10] has attracted much attention in one-way transmission of acoustic waves in recent years. Li et al [11] have demonstrated the unidirectional transmission of acoustic waves in the asymmetric system both numerically and experimentally.…”

Sonic crystal acoustic switch device

“…12,13 The unidirectional transmission effect has been used to develop acoustic rectifiers and acoustic diodes. [14][15][16][17] These developments promise continuing realization of complex acoustic structures designed for signal processing, 18 acoustic imaging, and sensor technologies. SCs are utilized in acoustic devices and applications that can efficiently guide and manipulate sound waves.…”

One-dimensional acoustic diodes based on the anisotropy of solid media and linear acoustics

“…This one-way effect of electrical currents is called rectifying phenomenon. Recently the rectifying phenomenon of energy of waves has attracted great interest in many fields, such as thermal diodes [1][2][3][4], electromagnetic diodes [5][6][7][8][9][10] and acoustic diodes [11][12][13][14][15][16][17][18][19][20][21][22], etc.…”
