High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning
Advanced Materials Technologies, EarlyView.High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

CPW-Fed Fractal Slot Antenna for UWB Application
International Journal of Antennas and Propagation, 2012 A novel printed ultrawideband (UWB) CPW-fed Koch fractal slot antenna is proposed. The UWB bandwidth is largely enhanced by the three-iteration Koch fractal slot whose extrusive angle is 900 instead of 600 to obtain better convoluted shape and self ...
