Suitability of pure nano crystalline LiF as a TLD dosimeter for high dose gamma radiation [PDF]

open access: yesNuclear Technology and Radiation Protection, 2018
LiF is an alkali halide that is commonly used in radiation dosimetry utilizing its well-known thermoluminescence property. Pure LiF has very limited use in radiation dosimetry since the density and types of the internal traps are limited.

Perspective method for reconfigurable intelligent surface design for NOMA transmission: Theoretical study

open access: yesFrontiers in Communications and Networks, 2023
The method (paradigm) presented here was inspired by two basic ideas: the assumption of the MIMO-RIS-NOMA communication channel as a dispersive channel with fading, and the representation of the latter by means of the generalized Kronecker channel model (

Performance of Multihop Wireless Links over Generalized-K Fading Channels [PDF]

open access: yes, 2010
The performance of multihop links is studied in this contribution by both analysis and simulations, when communicating over Generalized-K (KG ) fading channels. The performance metrics considered include symbol error rate (SER), outage probability, level

Rayleigh Fading Suppression in One-Dimensional Optical Scatters

open access: yesIEEE Access, 2019
A highly coherent wave is favorable for applications in which phase retrieval is necessary, yet a high-coherence wave is prone to encounter Rayleigh fading phenomenon as it passes through a medium of random scatters.
