  • Sleeved Dipole Antenna for Multi-Octave Broadside Radiation Pattern Control
    Publication number: 20200321701
    Abstract: A method of maximizing the radiation pattern at broadside of a dipole antenna. The antenna is formed with a dipole wire having a sleeve centered along the length of the dipole wire. This sleeve is made from a conductive material and has a length relative to the dipole length that causes the dipole antenna to have an elevation gain pattern that maintains a peak at zero elevation over a much greater bandwidth than a conventional dipole.

  • Method and apparatus to propagate crack growth in a workpiece
    Patent number: 9573284
    Abstract: A method and apparatus for forming a starter notch along the length of a work-piece for subsequent fatigue testing. The starter notch is formed with a cutting wire such that it will promote fatigue-cracking in the work-piece in one defined direction and avoids cracking in directions other than the length direction of the starter notch. Improved fatigue-testing analysis may therefore be realized.
