“…Accordingly, many types of mode conversion phenomena of guided waves have been reported. The most representative mode conversion phenomenon in guided waves in plates is the mode conversion between S0 and SH0 modes [73, 134,144,179,201,[203][204][205][206][207][208][209][210][211][212][213][214][215][216][217]. Unlike acoustic waves in fluids (which carry only longitudinal waves) and electromagnetic waves (which carry only transverse waves), an elastic solid medium can carry both longitudinal and transverse waves.…”

“…For example, Chen et al [404] proposed elastic metamaterials with space and time-modulated resonators, as illustrated in figure 22(a), and experimentally demonstrated non-reciprocal flexural wave propagation, such as the unidirectional bandgap behavior at 250 kHz. Non-reciprocal wave propagation can also be caused by elastic metamaterials with Willis coupling [209,[410][411][412][413][414][415] and nonlinearity [416][417][418]. Willis coupling is the coupling between the stress and velocity (or the strain and momentum), providing additional design freedom for enhanced wave functionalities.…”

Guided waves, elastic waves propagating through bounded structures, play a pivotal role in various applications, including ultrasonic non-destructive testing and structural health monitoring. Recently, elastic metamaterials artificially engineered to exhibit physical properties not typically seen in nature have emerged as a ground-breaking approach, heralding a new era in guided wave-based technologies. These metamaterials offer innovative solutions to overcome the inherent constraints of traditional guided wave-based technology. This paper comprehensively reviews elastic metamaterials from their fundamental principles to diverse applications, focusing on their transformative impact in guided wave manipulation.
