In this article, cylindrical and conical conformal arrays are presented to flexibly launch the OAM vortex beams. First, we analyze the characteristics of OAM beams generated by planar annular arrays with different radii. Then characteristics of vortex waves generated by cylindrical and conical arrays with different curvatures are analyzed. Finally, prototypes of cylindrical and conical arrays are...
Three-dimensional Integrated-circuit (3DIC) needs coatings with both high thermal conductivity and high electrical insulation for isolating electronic devices and interconnects while spreading heat generated by stacked integrated circuits effectively. Single crystalline diamond possesses excellent electrical insulation and thermal conductivity, which is a perfect candidate for the need by 3DIC. However,...
