Frozen water waves over rough topographical bottoms
Liang-shan Chen, Zhen Ye
The propagation of surface water waves over rough topographical bottoms is investigated by the multiple scattering theory. It is shown that the waves can be localized spatially thr…
Acoustic imaging and collimating by slabs of sonic crystals made from arrays of rigid cylinders in air
Liang-Shan Chen, Chao-Hsien Kuo, Zhen Ye
We show some new properties of the acoustic propagation in two-dimensional sonic crystals, formed by parallel rigid cylinders placed in air. The transmission through slabs of sonic…
Guiding optical flows by photonic crystal slabs made of dielectric cylinders
Liang-Shan Chen, Chao-Hsien Kuo, Zhen Ye
We investigate the electromagnetic propagation in two-dimensional photonic crystals, formed by parallel dielectric cylinders embedded a uniform medium. The frequency band structure…
Bandgaps in the propagation and scattering of surface water waves over cylindrical steps
Liang-Shan Chen, Chao-Hsien Guo, Zhen Ye +1
Here we investigate the propagation and scattering of surface water waves by arrays of bottom-mounted cylindrical steps. Both periodic and random arrangements of the steps are cons…
