By properly designing the NRMS, it can perform stable negative permeability and positive permittivity along the tangential direction of the NRMS within a wide band, which can be fully employed to suppress the mutual couplings of large-scale antenna arrays. At the same time, the proposed NRMS can also result in positive permittivity and permeability along the normal direction of the NRMS, which guarantees the free propagation of electromagnetic waves from antenna arrays along the normal direction. For demonstration, a 4\u00d74 dual-polarized antenna array loading with the proposed NRMS is designed to improve the isolations of the antenna array. The simulations demonstrate that the isolations among all ports are over 24 dB from 4.36 to 4.94 GHz, which are experimentally verified by the measured results. Moreover, the radiation patterns of antenna elements are still maintained after leveraging the proposed NRMS. Due to the simple structure of the proposed NRMS, it is very promising to be widely employed for massive MIMO antenna arrays.<\/jats:p>","DOI":"10.3390\/s23010152","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T02:53:11Z","timestamp":1672109591000},"page":"152","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Decoupling of Dual-Polarized Antenna Arrays Using Non-Resonant Metasurface"],"prefix":"10.3390","volume":"23","author":[{"given":"Shengyuan","family":"Luo","sequence":"first","affiliation":[{"name":"Antenna, Propagations and Millimeter-Wave Systems (APMS) Section, Aalborg University, 9220 Aalborg, Denmark"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3128-1963","authenticated-orcid":false,"given":"Peng","family":"Mei","sequence":"additional","affiliation":[{"name":"Antenna, Propagations and Millimeter-Wave Systems (APMS) Section, Aalborg University, 9220 Aalborg, Denmark"}]},{"given":"Yiming","family":"Zhang","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Optoelectronic Information Processing Chips and Systems, School of Electronics and Information Technology, Sun Yat-sen University, Guangzhou 510006, China"}]},{"given":"Gert Fr\u00f8lund","family":"Pedersen","sequence":"additional","affiliation":[{"name":"Antenna, Propagations and Millimeter-Wave Systems (APMS) Section, Aalborg University, 9220 Aalborg, Denmark"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9003-2879","authenticated-orcid":false,"given":"Shuai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Antenna, Propagations and Millimeter-Wave Systems (APMS) Section, Aalborg University, 9220 Aalborg, Denmark"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Face, K., Lee, J., and Jung, Y.
