We investigate nano-porous structures in thin low-dielectric films, i.e. the pore sizes, distributions, and interconnectivity, by using depth profiled positroni
We report the results of our investigation on the loss property of a birefringent photonic crystal fibre (PCF) basedon a particular periodic arrangement of air-
A new linear ultrasonic phased array fixed on a cylindrical surface is designed. This kind of the cylindrical phased array can meet the specific requirements of
We calculate the density of states, the squared optical matrix element along the x direction, and the band gap of Si nanosphere with radius r smaller than 1.2nm
We propose and develop a novel method to identify a chaotic system with time-varying bifurcation parameters via an observation signal which has been contaminate
