In this paper, we reported high speed optical test on polymeric optical waveguide array with embedded 45 masculine micro-mirrors on flexible substrate for out-of-plane optical interconnects. The waveguide array was bent with curvature ranging from 61 mm to 5mm. As the bending radius decreases, the average insertion loss increases from 3.4 dB to 7.7 dB for single-mode fiber (SMF) coupling and fr...

In this paper we discuss a hybridised method for FEM-BEM coupling. The coupling from both sides use Nitsche type approach to couple the trace variable. This leads formulation that is robust and flexible with respect approximation spaces can easily be combined as building block other methods. Energy error norm estimates convergence of Jacobi iterations are proved performance illustrated on some ...

Free-standing all-polymer microring resonator optical filters as prototypical elements in flexible integrated lightwave circuits are demonstrated. The fabrication and measurement methods are discussed. The measured spectrum shows good agreement with theoretical expectations. The crucial ‘critical’ coupling condition is achieved, resulting in a measurement limited 27 dB extinction of the filter ...

The present paper investigates monitoring of fatigue cracks of a metal structure using an eddy current micro sensor. Fatigue cracks tend to occur at bolt-jointed structures on an aircraft. In order to detect the damage quantitatively, a kind of change-prone micro eddy current sensor is designed and fabricated with flexible printed circuit board (FPCB) technology. A forward semi-analytical model...

This study’s overarching aim is to establish the areal extent and characteristics of the rapid sugarcane expansion and land use change in São Paulo state (Brazil) as a result of an increase in the demand for ethanol, using Landsat type remotely sensed data. In 2003 flex fuel automobiles started to enter the Brazilian consumer market causing a dramatic expansion of sugarcane areas from 2.57 mill...

Title of Dissertation: Flexible and Efficient Control of Data Transfers for Loosely Coupled Components Shang-Chieh J. Wu, Doctor of Philosophy, 2008 Dissertation directed by: Professor Alan Sussman Department of Computer Science Allowing loose coupling between the components of complex applications has many advantages, such as flexibility in the components that can participate and making it eas...

A flexible birdcage-type resonant RF detector for magnetic resonance imaging is described. The circuit consists of a polygonal ring of magnetically coupled L–C resonators, a periodic structure supporting backward magnetoinductive waves. The elements are mechanically linked to allow relative rotation, and the pivot point is optimised to hold the nearest-neighbour coupling coefficient invariant t...
