Ultra Low Outgassing, Focusing, and Hard Seal Capable Materials for HPM Radomes

Vector ElectroMagnetics proposes to continue the development of HPM radome solutions with ultra-low in-band internal reflection.  This will be accomplished with a combination of composite materials and FSS layers.  The FSS layers serve as impedance matching layers.  FSS layers will also be used to create a pass band at the operating frequency of the HPM system as well as out-of-band rejection at other frequencies.  Full wave computational electromagnetic CEM analysis will also continue in Phase II and will be used to predict far field antenna radiation as well as near field effects of the 3-D antenna system combined with the impedance matched radome.  Concurrently with the continuation of RF development, the radome will be designed with a hard seal in order to minimize outgassing of the radome material.  All of the proposed design and analysis activities will be verified through extensive fabrication and testing of coupons as well as complete full size radomes.
