Investigation of Mid-Infrared Millimeter Wave Radome with Polycrystalline Magnesium Fluoride

In this paper, the radome materials suitable for mid-infrared /millimeter wave multimode were introduced, as well as the properties. In comparison with the difference of the radome materials, the polycrystalline magnesium fluoride was promising for the radome of mid-infrared /millimeter wave multimode. Furthermore, the millimeter wave transparent properties of polycrystalline magnesium fluoride were studied by the simulation based on moment method and multilevel fast multipole method.
