Fused silica is widely used as a material for optical lenses owing to its excellent properties and low thermal expansion coefficient. However, hard brittle material, there very limited option of processing technologies machining fused with surface structures. In this paper, picosecond laser based single crystal diamond tool fabrication technology proposed generate micro milling tools different ...

This letter describes a wideband circularly polarized (CP) array antenna with 2 × alignment of sequentially rotated CP patch elements. Each element has diamond-shaped artificial ground structure (DAGS), which extend the 3-dB axial ratio (AR) bandwidth antenna, and elements in are fed relative phases 0°, 90°, 180° 270°. The main purpose this work is to show potential AR by combination DAGS seque...

A general mathematical model based on the principal of non-equilibrium thermodynamics is proposed for analyzing the energy consumption of trayed column distillation processes related the tray structures, which can be used not only to calculate the energy consuming in different operational conditions, but also, and more importantly, to evaluate the entropy generation rate (EGR) of the different ...
