Abstract: A method for providing a shock penetration resistant apparatus may include providing an item of protective gear to be positioned proximate to an object to be protected, and disposing a shock penetration resistant material proximate to the item of protective gear to attenuate or redirect shock pulses away from the object to be protected. An apparatus is also provided that may include an item of protective gear and a shock penetration resistant material. The item of protective gear may be configured to be positioned proximate to an object to be protected. The shock penetration resistant material may be disposed proximate to the item of protective gear to attenuate or redirect shock pulses away from the object to be protected.

Abstract: A phased array antenna system may include a sheet of conductive material with a plurality of aperture antenna elements formed in the sheet of conductive material. Each of the plurality of aperture antenna elements is capable of sending and receiving electromagnetic energy. The phased array antenna system may also include a wide angle impedance match (WAIM) layer of material disposed over the plurality of aperture antenna elements formed in the sheet of conductive material. The WAIM layer of material includes a plurality of metamaterial particles. The plurality of metamaterial particles are selected and arranged to minimize return loss and to optimize an impedance match between the phased array antenna system and free space to permit scanning of the phased array antenna system up to a predetermined angle in elevation.
