1. An area-protection system comprising:

  • sensors to detect an intruder within a protected area;

    an active-array antenna to generate a high-power millimeter-wave wavefront to deter the intruder when detected within the protected area; and

    one or more reflectors positioned within the protected area to help retain energy of the wavefront within the area,wherein the active-array antenna comprises a plurality of semiconductor wafers arrnged together on a substantially flat surface, each semiconductor wafer including a power amplifier and a transmit antenna which together generate the high-power millimeter-wave wavefront.
