A ‘sandwish’ artificial electromagnetic structure was proposed for meeting the stealth satellite radome's requirements. This structure is implemented by synthetically utilizing the transmission functional layers and absorbing functional layers. Simulating calculation indicate the proposed structure has less-than 3dB insertion loss in the range of 1GHz-8.5GHz and more-than 0.8 absorptivity in the range of 11.5GHz-18GHz, while keeping incident-angle stability. The proposed artificial electromagnetic structure has important project application values for stealth satellites.
