Optical metamaterials generally refer to artificial composite structural materials that achieve optical properties not possessed by traditional materials through the artificial design of sub-wavelength structural units.In the ultraviolet，visible or infrared bands，the permittivity and permeability of optical matematerial can break through the limit constraints of traditional materials.And optical materials are expected to show great application potential in aerospace fields such as detection，communication，stealth，power，and thermal control.This paper mainly elaborates on the important subsystems of aerospace equipment and then proposes possible future application scenarios of optical metamaterials.And then，the research progress of optical metamaterials in the face of these application scenarios are summarized.
