Development of a new approach for high-quality quadrupling frequency optical millimeter-wave signal generation without optical filter
(PIER, 2013)
In this paper, we propose a new approach to generate quadrupling-frequency optical millimeter-wave (mm-wave) signal with carrier suppression by using two parallel Mach-Zehnder modulators (MZMs) in Radio-over-fiber (RoF) ...
Shear speed analysis on Sn-3.9Ag-0.6Cu Solder
(Trans Tech Publications (TTP), 2013)
Ball Grid Array (BGA) is a type of semiconductor interconnection used in Integrated Circuit (IC) which is being scaled down to micro and nano size. The reliability of BGA in IC becomes a concern as the size of IC reduces. ...
Improved debye model for experimental approximation of human breast tissue properties at 6 GHz ultra-wideband centre frequency
(Engg Journals Publications, 2013)
This paper investigates complexity of breast tissue structure and mathematical equations to describe their dielectric properties. Experimental breast tissue dielectric properties are compared to theoretical results from ...
