Different from conventional absorbers, the absorption behavior is much less deteriorated with the increase in the incidence angle. Two hybrid resonators, which are realized by symmetrical graphene patterns, are employed to obtain the desired broadband and polarization-insensitive absorption performance. The optimal impedance-matching behavior is designed at the oblique incidence of electromagnetic waves, and an equivalent circuit model is used to analyze and facilitate the mechanism of the proposed absorber. The results indicate that the absorber can maintain a stable absorption performance with a fractional bandwidth (FWB) of 136.4% up to 40\u00b0. With these performances, the proposed UWB absorber could be more competitive in aerospace applications.<\/jats:p>","DOI":"10.3390\/s23052677","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T02:02:56Z","timestamp":1677636176000},"page":"2677","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["UWB Frequency-Selective Surface Absorber Based on Graphene Featuring Wide-Angle Stability"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5198-1556","authenticated-orcid":false,"given":"Zhefei","family":"Wang","sequence":"first","affiliation":[{"name":"School of Electronic and Information Engineering, Nanjing University of Information Science and Technology, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2484-7495","authenticated-orcid":false,"given":"Jiajun","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Nanjing University of Information Science and Technology, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongjiao","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Nanjing University of Information Science and Technology, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingsheng","family":"Zeng","sequence":"additional","affiliation":[{"name":"College of Astronautics, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5051-3304","authenticated-orcid":false,"given":"Mingxin","family":"Song","sequence":"additional","affiliation":[{"name":"College of Applied Technology, Hainan University, Danzhou 571737, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tayeb A.","family":"Denidni","sequence":"additional","affiliation":[{"name":"Institut National de la Recherche Scientifique, Universit\u00e9 du Quebec, Montreal, QC H5A 1K6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"376","DOI":"10.1109\/JSTQE.2009.2031618","article-title":"A planar metamaterial with dual-band double-negative response at EHF","volume":"16","author":"Gundogdu","year":"2009","journal-title":"IEEE J.
