Abstract
A compensated radome is provided, comprising an inner layer of a negative index of refraction material, often referred to as a “metamaterial”, and an outer layer of a positive index of refraction material. The thickness of the two materials and their respective refractive indices are adjusted so that a beam of light passing through the radome is effectively not refracted. The metamaterial-compensated radomes solve the bore sight angle problem with a minimum of complexity.
Claims20
A compensated radome, comprising an inner layer of a negative index of refraction material and an outer layer of a positive index of refraction material, wherein each layer has a thickness, with said thickness of each layer and their respective refractive indices adjusted so that a beam of electromagnetic radiation passing through said radome is effectively not refracted.
A missile including a radome, said radome compensated against bore sight error, said radome comprising an inner layer of a negative index of refraction material and an outer layer of a positive index of refraction material, wherein each layer has a thickness, with said thickness of each layer and their respective refractive indices adjusted so that a beam of electromagnetic radiation passing through said radome is effectively not refracted.
