Transmission beam can be modulated at the liquid-liquid interface inside an electrowetting liquid lens.The fluctuation characteristics of the interface has a decisive effect on the beam modulation.A closed cylinder in capillary constant scale is analyzed and the natural frequencies of a flat interface are obtained using capillary wave hydrodynamics.Results in modes 0 and 1 are in good agreement with previous experiments in the literature.The influences of the radius,the height ratio and the height-to-diameter ratio of a liquid lens on the interface eigenfrequencies are analyzed.

Dynamics analysis of a 5-dimensional hyperchaotic system with conservative flows under perturbation
Conservative chaotic flows have better ergodicity,therefore researching dynamics and applications of conservative systems has become a hot topic.We introduce a constant-perturbation into a 5-dimensional(5D)conservative model.Consequently,the line equilibr

Breathers and solitons for the coupled nonlinear Schr?dinger system in three-spine α-helical protein
We mainly investigate the variable-coefficient 3-coupled nonlinear Schr?dinger(NLS)system,which describes soli-ton dynamics in the three-spine α-helical protein with inhomogeneous effect.The variable-coefficient NLS equation is transformed into the consta

Progress in functional studies of transition metal borides
In recent years,transition metal borides(TMBs)have attracted much attention because they are considered as potential superhard materials and have more abundant crystal structures compared with traditional superhard materials.So far,however,no superhard ma
