Abstract

Metal-coated graphite whiskers with high strength-to-weight ratios appropriate for self-oriented antenna use (where the torque of the electric field moves the antenna to optimum position) may be produced economically on a continuous roller whisker growing system. Very robust plated graphite antennae of optical and infrared wavelengths can be grown with accurate control of length and with diameters as small as 15 nm. With a whisker in use as an antenna, the dipole moment induced in a whisker by the electric vector of polarized electromagnetic waves reacts with that electric field to produce a torque tending to align the whisker with the electric vector of the polarized electromagnetic wave.
