Subdiffraction Focusing Enabled by a Fano Resonance

Physical Review X, 2014
Radiationless electromagnetic interference (REI) has been used to achieve focusing below Abbe’s diffraction limit. Here, we demonstrate an approach to REI that uses the Fano resonance of subwavelength slits to achieve subdiffraction focusing.

Space localization algorithm based RSSI in wireless sensor networks

Tongxin xuebao, 2009
In real measurement environment,some factors of multi-path,diffraction,obstacles,etc.,propagation losses produced location errors in the positioning process by RSSI technology.Through analyzing error range in 3D space,a new spatial locating algorithm ...
