摘要：
A transparent ultrawideband absorber based on petal structure was presented, and the theoretical and simulation analysis was carried out. The microwave absorber combined PET and ITO film, and the whole structure was ITO-PET-ITO sandwich structure. The absorber achieved a good absorption rate of more than 90% in the 33 GHz-54.5GHz frequency band. Among the transparent metamaterial absorbers, the highest relative absorption bandwidth (above 90%), 49.14%, In addition, the absorber was insensitive to TE and TM modes. There are reasons to believe that the absorber will have a broad application prospect in the electromagnetic stealth field.
