Title:
光学的に再設定可能な高周波アンテナ
Document Type and Number:
Japanese Patent JP5518728
Kind Code:
B2
Abstract:
Optically reconfigurable radio frequency antennas for use in aircraft systems and methods of its use are disclosed. In one embodiment, the antenna includes a surface-conformal reflector that includes optically addressable carbon nanotubes. The nanotubes can be combined with light-sensitive materials so that exposure to light of the correct wavelength will switch the nanotubes back and forth between a metallic and non-metallic state. The antenna has a transmitter that radiates a radio frequency signal in the direction of the surface illuminator and an addressable optical conductor to illuminate the nanotubes with one or more optical signals. When the domains are illuminated they switch portions of the carbon nanotubes between its non-metallic states and metallic states to reflect the radiated radio frequency signal.
