摘　　要：In this paper,an optically transparent broadband absorbing metamaterial is designed for electromagnetic protection and stealth for visible parts of ships.Based on the coupling resonance loss of double-lay metamaterial structure,the new absorbing material realizes broadband characteristics.Based on the photoelectric compatibility characteristics of graphene thin films,the new absorbing material realizes high transmittance characteristics.The measured results show that when the absorbing rate is higher than 90%,the bandwidth of the absorbing metamaterial is 7.95—18.65 GHz,covering X-band(7.95—12 GHz)and Ku-band(12—18.65 GHz),and the visible light transmittance is 85%.The design and preparation of new absorbing material can solve electromagnetic compatibility(EMC)design problems of high transmittance and broadband.It can be widely used in observation windows of ships,aircraft and reconnaissance control vehicle,display terminal of the information system.
