  • EFFICIENT METAMATERIAL-INSPIRED ELECTRICALLY-SMALL ANTENNA
    Publication number: 20090140946
    Abstract: Planar (two-dimensional) and volumetric (three-dimensional), metamaterial-inspired, efficient electrically-small antennas. The electric-based and magnetic-based antenna systems are shown to be naturally matched to a source and are linearly scalable to a wide range of frequencies. The systems include a radiating element that is fed by the source through a finite ground plane via a feedline and an electrically-small, one-unit cell made of a metamaterial that is adapted to match the input impedance of the antenna.

  • Electromagnetic or other directed energy pulse launcher
    Patent number: 4959559
    Abstract: The physical realization of new solutions of wave propagation equations, such as Maxwell's equations and the scaler wave equation, produces localized pulses of wave energy such as electromagnetic or acoustic energy which propagate over long distances without divergence. The pulses are produced by driving each element of an array of radiating sources with a particular drive function so that the resultant localized packet of energy closely approximates the exact solutions and behaves the same.
