Innovative Hardware Technologies for Anti-Jam and Electromagnetic Attack Rejection in Radars

The proposed research promises to complement research success regarding the planar metamaterial limiter coating (PMLC) and will research applications to electromagnetic interference (EMI) shielding. This would enable design engineers to support radar, communication, and global positioning satellite (GPS) systems by applying an advanced shielding technology that counters evolving threats while not affecting the existing hardware design. This research will provide the basis for the development of PMLC and Shielding Effectiveness (SE) that will counter this problem and provide the necessary growth potential for evolving threats. During the proposed Second Phase II effort, PMLC-SE technical feasibility demonstrations will be performed to demonstrate that this PMLC-SE technology will increase shielding effectiveness several orders of magnitude while increasing the bandwidth which will allow countering the estimated interference and high power microwave (HPM)/electromagnetic pulse (EMP) threats without transient interference failure or permanent damage. The intended PMLC-SE operation principle is to establish virtually instantaneous energy exchange between nonlinear PMLC coating material and incident EMI, thus negating these fields. This effect will be achieved using nonlinear properties of the PMLC-SE constituent material when influenced by EMI. This research will provide a new category of inexpensive, easily integrated shielding technology that can grow with the evolving threat. Approved for Public Release 15-MDA-8169 (20 March 15)
