Angular-asymmetric transmitting metasurface and splitter for acoustic wave: a combining of the Coherent Perfect Absorber and Laser
Shuting Cao, Zhilin Hou
Coherent Perfect Absorber (CPA) and Laser is a pair of inversely worked wave structure satisfying the time-reversal relation. We point out that, if the wave energy absorbed by CPA…
Highly efficient acoustic refractive metasurfaces by harnessing near field coupling
Zhilin Hou, Xinsheng Fang, Yong Li +1
Typical acoustic refractive metasurfaces governed by generalized Snell law require several types of subwavelength subunits to provide an extra phase gradient along the surface. Thi…
Perfect anomalous splitter by acoustic meta-grating
Huiqin Ni, Xinsheng Fang, Zhilin Hou +2
As an inversely designed artificial device, metasurface usually means densely arranged meta-atoms with complex substructures. In acoustics, those meta-atoms are usually constructed…
Tunable elastic Parity-Time symmetric structure based on the shunted piezoelectric materials
Zhilin Hou, Badreddine Assouar
We theoretically and numerically report on tunable elastic Parity-Time (PT) symmetric structure based on shunted piezoelectric units. We show that the elastic loss and gain can be…
Quasi-unit cell description of two-dimensional octagonal quasilattice
Longguang Liao, Xiujun Fu, Zhilin Hou
We present a cluster covering scheme to construct the two-dimensional octagonal quasilattice. A quasi-unit cell is successfully found which is a two-color cluster similar to the Gu…
