DOI: 10.1016/j.wavemoti.2021.102729
Abstract: Abstract We consider the effective wave motion, at spectral singularities such as corners of the Brillouin zone and Dirac points, in periodic continua intercepted by compliant interfaces that pertain to e.g. masonry and fractured materials. We… read more here.
