Haleakala R&D Inc. will advance state of the art in antenna radomes. We propose to use our plasma frequency selective surface radomes with plasma tubes embedded in an ultra-light and ultra strong synthetic foam material.We will compare this to metal FSS radomes with slots filled with synthetic foam and hybrid plasma-metal frequency selective surface radomes. We will research plasma FSS with plasma tubes embedded in synthetic foam, and metal slot FSS filled with Synfoam, and hybrid models to meet the Navy goals for superior radomes. We are purchasing this material for our technologies and we have examined samples. Our phase one effort will include characterizing plasma frequency selective surfaces, plasma cylindrical annular rings made of Synfoam, compare plasma FSS embedded in synthetic foam with metal FSS with Synfoam embedded in the slots, and hybrid metal plasma FSS with synthetic foamsupport structures. We will test these designs from 0 up to 40 or 100 GHz (Ka or W-band), and thermal modeling. We will investigate machined and cast radomes, plasma FSS radomes with tubes embedded in synthetic foam, metal slot radomes with slots filled with Synfoam, , and hybrid models with the apertures filled with synthetic foam
