Abstract: A C-sandwich radome structure includes a first core, an outer skin layer on the first core, a second core, and an inner skin layer on the second core. An intermediate skin layer is disposed between the first core and the second core and the intermediate skin layer includes a dielectric enhancer for raising the dielectric constant of the intermediate skin layer so the intermediate skin layer can be made thinner to reduce the weight and cost of the structure while maintaining the electrical transmission performance of a thicker, heavier intermediate skin layer.

Abstract: A B-sandwich radome structure including a structural layer, an inside matching layer adjacent one side of the structural layer, and an outside matching layer adjacent an opposite side of the structural layer. Both matching layers are made of formable sheet material assembled with the structural layer during shaping of the radome and co-cured with the structural layer resulting in a rigid final form of the radome.
