Abstract: Abstract Many engineering applications involve slender tubular structures subjected to potentially harmful vibrations that must be damped to sustain the working life of the system. This research takes recent experimental observations involving cylindrical metamaterials, ideal… read more here.

Abstract: The acoustic black hole (ABH) structure exhibits remarkable energy focalization above a given cut-on frequency, offering potential for broadband vibration suppression in structures. However, its energy focusing properties diminish significantly below this cut-on frequency. Therefore,… read more here.
