TL;DR: In this article, the authors proposed the systematic design of ultra-broadband passive metasurfaces by combining the broadband local reflection rule with an optimization method, which can reshape a reflected wavefront rather arbitrarily, despite being much thinner than the wavelength, allowing on-demand wavefront modulation in a variety of applications.

TL;DR: In this article, the wave propagation and localization in randomly disordered periodic multi-span beams on elastic foundations are studied and the transfer matrices between two consecutive sub-spans are obtained by means of the continuity conditions.

TL;DR: In this paper, a sub-interface crack in a bi-material is studied with emphasis on the dynamic interaction between the crack and the interface, by combining the traditional time-domain displacement boundary element method (BEM) and the non-hypersingular traction BEM.

TL;DR: In this paper, a multi-layered model for fracture analysis of functionally graded materials with arbitrarily varying Young's modulus and Poisson's ratio under plane stress-state deformation has been developed.

TL;DR: In this article, the free vibration of the variable thickness beam made of functionally graded materials (FGMs) which is submerged in fluid is studied. But the authors assume that material properties follow the power law distribution along the thickness direction.
