摘要: We calculated the frequency ω versus wave vector K for elastic waves propagating in both thick and thin plates consisting of solid inclusions placed periodically host material. were particularly interested possible creation spectral gaps (stop bands) all directions propagation bending waves. found that Mo, Fe, steel, or Pb forming a two dimensional hexagonal lattice Lucite give rise to gaps.
