TL;DR: This communication presents a new antenna system designed for cognitive radio applications that has been simulated with the driving motor being taken into consideration and a good agreement is found between the simulated and the measured antenna radiation properties.

TL;DR: By utilizing a latch that is radiation hard at static clock frequencies the errors due to transients could be separated and the pulse structure of the propagating transients was studied using SPICE, and the implications of these pulsewidths will be discussed.

TL;DR: In this article, single event transients (SETs) in digital circuits/processes are examined and shown to substantially mitigate traditional SEU static-latch hardening techniques below 0.25 /spl mu/m.

TL;DR: In this paper, a new test structure was designed for measuring the pulsewidths of transients created by SETs and experimental data was gathered using heavy ions from LETs of 11.5 to 84MeV-cm/sup 2/mg.

TL;DR: A cognitive radio front end using an optically pumped reconfigurable antenna system (OPRAS) is investigated, and comparisons are made to other commonly used switching techniques for reconfigurability, such as techniques based on PIN diodes and RF microlectromechanical systems integration.
