Furthermore, after deriving the boundary-finite element (Hybrid) formulations, the solvable matrix of the equations in the discretized form is presented. In a novel approach, by estimating the temporal variations of the element nodes using Taylor and Fourier series, a time series discrete matrix is introduced for solving the equations which provides a higher degree of accuracy in compare to other time discretization approaches.

In fractured or faulted media, Rayleigh waves show anisotropic velocities that could provide information on the fault properties. However, the exact relationship between Rayleigh wave anisotropy and true anisotropic structures is not well known. This study used a three-component (3C) beamforming toolbox to analyse numerical full waveform seismic wave propagation from conceptual models of fractured media, which depict the nonlinear physical behaviour of the wave. We identify Rayleigh waves in the synthetic data produced from a single point source at different locations, compare observed Rayleigh wave anisotropy to structural anisotropy, and assess the effect array design and source distance have on Rayleigh wave analysis and observed anisotropy. Numerical analysis shows that the smaller the velocity contrast between fault and surrounding rock, the more complex the anisotropic response. We find that the slow directions of Rayleigh wave propagation can be a better indicator of fault strike than the fastest direction, when the velocity contrast between the two media is small.</div></div>","PeriodicalId":49367,"journal":{"name":"Wave Motion","volume":"139 ","pages":"Article 103596"},"PeriodicalIF":2.1,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remarkably, we unveil the formation of genuinely sub-wavelength Bragg-like band-splitting induced bandgaps, generalizing the \"band-folding induced bandgaps\" in the literature. Additionally, we propose a methodology to widen sub-wavelength local resonance bandgaps by hosting two local resonances within the same bandgap. These sub-Bragg phenomena are realized at low frequencies in an axisymmetric vibroacoustic metamaterial consisting of repetitive multilayered unit cells, each composed of two layers of membrane-cavity resonators. The coupled sound-structure interaction is solved exactly. The studied system exhibits sub-wavelength acoustical transparency, akin to “electromagnetically induced transparency”, and an acoustic analogue of \"plasma oscillations\". We derive canonical conditions for the emergence of band-splitting bandgaps, showing they are exclusive to multilayered configurations. These band-splitting bandgaps resemble Bragg bandgaps in their attenuation, band-crossing capabilities, and potential to host topological interface states. We also reveal that classical geometric Bragg diffraction does not apply to the periodic multilayered vibroacoustic configurations examined. The studied sub-wavelength phenomena unlock new possibilities for controlling low-frequency wave propagation in the sub-Bragg regime. Design guidelines for maximizing bandgap width within the low-frequency regime are provided, and the attenuation performance across different bandgaps is demonstrated through numerical simulations. We anticipate that our findings, while demonstrated here in vibroacoustic metamaterials, provide a promising approach for advanced acoustic devices, and could inspire future work exploring similar sub-wavelength mechanisms in other classes of physical systems.</div></div>","PeriodicalId":49367,"journal":{"name":"Wave Motion","volume":"139 ","pages":"Article 103601"},"PeriodicalIF":2.1,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
