US Patent 7132994 - Resonant Nanotube Antenna

This patent from Ambit Corp. has priority going back as early as 1997 and lays the basic foundation for the use of arrays of nanotubes as antenna elements responsive to optical wavelengths. It is interesting to note that Ambit Corp. also has a fundamental patent for nanotube-based actuators (US 7099071). Claim 1 reads:

1. A resonant nanotube structure responsive to electromagnetic energy, said nanotube structure comprising: a substrate; and an ordered array of resonant nanotubes arranged on said substrate.
