This paper presents the design, fabrication and measurement results of a nano-photonic bandgap crystal (PhC) integrated circuit device. The PhC comprises of orthogonally intersecting single line defect Bragg reflection waveguides, partially reflecting PhC mirrors and a small volume optical resonator. A PhC bandgap optical intersection with size of ~ 5 × 5 um, waveguide width of 800 nm, and oper...
280 control on advanced, high-speed flight vehicles. Effective manipulation of a flow field using flow-control technologies can lead to a number of significant benefits to aerospace vehicle systems, including enhanced performance, maneuverability, payload, and range, as well as lowered overall cost. A research team led by APL is investigating the time-dependent fluid dynamic interactions betwee...
this paper presents a sensorless system drive on primary flux oriented control (pfoc) and secondary flux oriented control (sfoc) for the linear induction motor (lim) with taking into account end effect. extended kalman filter (ekf) is applied to estimate lim speed by measuring motor voltages and currents. in order to achieve desirable dynamic and robustness motor performance instead of traditio...
