This work investigates the mechanism of generation of undesired common-mode (CM) currents in differential-line interconnects with slight non-uniformity owing to imperfect production process. To this end, three different non-ideal configurations are considered, obtained by perturbation of an ideally-uniform differential interconnect composed of two microstrips. By resorting to modal analysis, the governing...
In this paper, we propose a formation control algorithm for multi-agent systems to achieve prospected formation shape and track reference trajectory. We assume the description of formation and reference velocity is known to all agents. For second-order dynamics, we present a strategy that allows all agents to maneuver to desired scaled formation during tacking leader's movements. Finally, simulation...
The rare-earth manganites R1−xAxMnO3 have stimulated considerable scientific and technological interest in recent years due to their exotic electronic and magnetic properties [1]The fascinating physics of these materials is driven by a close coupling between charge, spin, lattice and orbital degree of freedom, which has commonly resulted in phase separation between charge/orbital order (COO) and ferromagnetic...
Growth and characterization of graphene grown using copper foils as well as copper films on silicon dioxide on silicon substrates were performed. Kinetics of growth and effective activation energy for the graphene synthesis will be discussed for the surface catalytic synthesis of graphene. Conditions for large-scale synthesis of monolayer graphene will be addressed in this talk. Wafer-scale graphene...
The PHENIX Hadron Blind Detector (HBD) was successfully operated during the 2009 high energy polarized proton run at RHIC. This was the first data taking run after the detector was rebuilt following its first commissioning run in 2007. The detector was operated for several months under actual beam conditions and showed greatly improved performance over the commissioning run. Results are given on the...
The Micropen?? direct-write technique was used to fabricate ceramic skeletal structures to develop ceramic/polymer (2-2) composites for high frequency transducers in medical imaging applications. Both regular and volume fraction gradient (VFG) patterns were designed. By this approach, transducers were fabricated with 1 cm2 transduction area, operating at 4??5 MHz. The composites had ~30 vol% of ceramic,...
