This　paper　presents　an　analysis　of　the　resonance　principles　of　split-ring　metasurfaces　in　the　microwave　band.　We　examine　the　resonance　characteristics　of　U-shaped　rings　in　the　microwave　band　and　investigate　the　impact　of　different　degrees　of　disorder　on　the　resonance　characteristics.　For　two　cases　where　the　polarization　direction　of　the　electromagnetic　wave　is　parallel　and　perpendicular　to　the　opening　of　the　U-shaped　ring.　The　results　reveal　that　resonances　of　different　orders　exhibit　different　responses　to　positional　disorder.　In　the　case　of　the　polarization　direction　parallel　to　the　opening　of　the　U-shaped　ring,　the　two　main　resonance　modes　exhibit　different　behaviors　with　positional　disorder.　The　first-order　resonance　is　incoherent　and　the　second-order　resonance　is　coherent.　When　the　polarization　direction　of　the　electromagnetic　wave　is　perpendicular　to　the　opening　of　the　U-shaped　ring,　the　resonances　also　exhibit　coherent　behavior.　Our　research　findings　will　effectively　promote　the　development　of　disordered　metasurfaces　technology　and　provide　a　relevant　theoretical　basis　for　the　application　of　metamaterials　in　the　field　of　remote　sensing　detection.　©　2023　IEEE.
