Research on advancing chromatic reproduction and luminosity of a WLED using triple-layer remote phosphor arrangement
In this study, the use of triple-sheet phosphor arrangement (TRP) in
performing significant improvements to both color quality and luminous
flux of white light emitting diode (WLEDs) is introduced. The phosphor
layer of CaLaB3O7:Ce3+,Mn2+ is to…

The better distant phosphor configurations for enhancing WLED color intensity: YVO4:Eu3+ and YF3:Mn2+
The distant phosphor configuration produces more illuminating beams than the
two settings containing conformal or in-cup phosphor. When this configuration
is used, though, it is difficult to manage the color standard of light-emitting
diodes…

Design and manufacturing of iris waveguide filters for satellite communication
We propose in this paper, two bandpass filters in waveguide technology having
rectangular symmetrical discontinuities with a half-radius r, designed and
operating respectively in the X-Band (9−11.5) GHz and C-Band (3.5−5.5) GHz.
These filters…

Enhance iris segmentation method for person recognition based on image processing techniques
The limitation of traditional iris recognition systems to process iris images
captured in unconstraint environments is a breakthrough. Automatic iris
recognition has to face unpredictable variations of iris images in real-world
applications. For…
