Flexural wave band-gaps in phononic metamaterial beam with hybrid shunting circuits被引量：6
《Chinese Physics B》2015年第3期269-274,共6页张浩 温激鸿 陈圣兵 王刚 温熙森 
supported by the National Natural Science Foundation of China(Grant Nos.51275519 and 51175501)
Periodic arrays of hybrid-shunted piezoelectric patches are used to control the band-gaps of phononic metamaterial beams. Passive resistive-inductive （RL） shunting circuits can produce a narrow resonant band-gap （R...
