Harmonic boundary excitation of localized oscillatory waves in a mass-in-mass metamaterial is studied. It is shown that switch-on/off of the boundary excitation gives rise to a formation of a sequence of such waves, which propagate keeping its form and velocity. The wave formation is achieved only outside the band gap interval of the excitation frequencies. The boundary reflection of the localized oscillatory waves is observed and analysed.

超材料中局域振荡波的边界激发

研究了质中质超材料中局域振荡波的谐波边界激励。结果表明，边界激励的开/关会形成一系列此类波，这些波的传播保持其形式和速度。只有在激励频率的带隙间隔之外才能形成波。观察和分析局域振荡波的边界反射。
