Thanks for choosing this story. Please note that the graphene device in question does not "operate" at 26 GHz, but that this frequency is based on an extrapolation from data up to 10 GHz. 10 GHz is the highest frequency "achieved" by this transistor. See figure 6 in the paper.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
