We report cross-section measurement and propagation measurement of modes of large mode area holey fibers using near-field scanning optical microscopy (NSOM). Mode profiles are measured at the fiber end face using a scanning optical fiber tip held 10 nm from the surface, and compared to theoretical models. Both amplitude and phase of the electric field of the propagating light is measured using ...

This paper presents faster Specific Absorption Rate (SAR) measurement techniques based on a previously proposed estimation method. This estimation method theoretically estimates the SAR from a 2-D scanned electric field (E-field) by basically applying the equivalence theorem and the image theory. The method reduces the SAR measurement time without sacrificing accuracy. We present the applicabil...

We demonstrate the use of a single trapped ion as sensor to probe electric-field noise from interchangeable test surfaces. As proof principle, we measure magnitude and distance dependence two ion-trap-like samples with patterned Au electrodes. This trapped-ion could be combined other surface characterization tools help elucidate mechanisms that give rise ion-trap Such presents significant hurdl...

This paper presents a critical survey on different application of Phasor Measurement Units (PMUs) in electric power system networks incorporated with FACTS controllers for advanced power system operations, monitoring, control, and protection. Also this paper presents the current status of the research and developments in the field of the applications of PMUs in electric power system networks in...
