Secure Communication Channels Using Atmosphere-Limited Line-of-Sight Terahertz Links

open access: yesIEEE Transactions on Terahertz Science and Technology, 2022
Terahertz wireless links offer great promise for realizing physical-layer security due to the high directionality and the high path loss. In this work, we investigate the resilience against eavesdropping attacks in a directional terahertz link which ...

Effect of Ultraviolet Irradiation on 4H-SiC PiN Diodes Characteristics

open access: yesNanoscale Research Letters, 2021
In this paper, the effect of ultraviolet (UV) irradiation on the static characteristics of high voltage 4H-SiC PiN is investigated. No significant change is observed in the forward on state characteristic of 4H-SiC PiN diodes before and after ultraviolet
