Autor: Jyoti Biswas, Luca Cultrera, Wei Liu, Erdong Wang, John Skaritka, Kim Kisslinger, S. D. Hawkins, S. R. Lee, J. F. Klem

Publikováno v: AIP Advances, Vol 13, Iss 8, Pp 085106-085106-5 (2023)

Photocathodes based on GaAs and other III–V semiconductors are capable of producing highly spin-polarized electron beams. GaAs/GaAsP superlattice photocathodes exhibit high spin polarization; however, the quantum efficiency (QE) is limited to 1% or

Autor: S. R. Lee, E. H. Lim, F. L. Lo, K. H. Tan

Publikováno v: Radioengineering, Vol 26, Iss 4, Pp 984-991 (2017)

This paper presents a dielectric resonator antenna (DRA) reflectarray unit element with multiple loading circular slots underneath in concentric form. The radii of the three slots are varied simultaneously to function as phase-shifting elements. For

Broadband Single-layer E-Patch Reflectarray

Autor: S. R. Lee, E. H. Lim, F. L. Lo

Publikováno v: Radioengineering, Vol 26, Iss 1, Pp 97-106 (2017)

E-shaped patch resonator is proposed for designing a novel broadband linearly polarized reflectarray for the first time. The element is made up of a shorted E-shaped patch with a polystyrene foam placed beneath it, and no dielectric substrate is need
