Routability is one of the primary objectives in placement. There have been many researches on forecasting routing problems and improving routability in placement but no perfect solution is found. Most traditional routability-driven placers aim to improve global routing result, but true routability lies in detailed routing. Predicting detailed routing routability in placement is extremely difficult...
A novel single-polarization photonic crystal fiber wavelength splitter based on hybrid-surface plasmon resonance is proposed. A full-vector finite-element method is applied to analyze the guiding properties. Numerical simulations show that the proposed splitter, which is only several hundred microns in length, gives single polarization in the 1.31- $\mu\hbox{m}$ and 1.55- $\mu\hbox{m}$ bands. The...
Measurement of transmission lines galloping amplitude is the very important part of wire monitoring. Aimed at reducing errors of the method, this paper presents a improved method which applies acceleration transducer for getting the precise values of galloping amplitude. This paper states the fundamental of the way using acceleration transducer to measure wires' galloping acceleration and then bring...
In this paper, self-made fretting fatigue wear test-bed was used to investigate fretting fatigue and wear properties of overhead transmission line between the strands, and then the fretting fatigue fracture life and the fracture surface microscopic morphology of ACSR in different testing conditions was analysed. The results show that under larger included angle, larger ACSR tensile force and larger...
