Abstract :
We show that convergent or divergent zoom lenses with focal length variations up to approximately 100% can be implemented by growing arrays of carbon nanotubes (CNTs) on curved templates. Unique lenses, which can change their character from divergent to convergent, can also be implemented in this way. Analogously, variable phase shifters with huge phase variation can be fabricated by growing arrays of CNTs on planar templates.
