Elastic Wave Modulation in Hollow Metamaterial Beam With Acoustic Black Hole

Elastic Wave Modulation in Hollow Metamaterial Beam With Acoustic Black Hole

We propose and discuss the elastic wave attenuation of hollow metamaterial beam embedded acoustic black hole. More abundant physical phenomena are given by modal analysis, shows that the band gap of three-dimensional acoustic black hole metamaterial is different from two-dimensional one. Lateral fle...
