Metamaterial　absorption　technology　plays　an　increasingly　important　role　in　military　and　civilian　sectors,　serving　crucial　functions　in　communication,　radar　technology,　and　electromagnetic　cloaking.　However,　traditional　metamaterial　absorbers　are　predominantly　composed　of　periodic　structures,　thus　limiting　their　absorption　bandwidth,　polarization,　and　angular　flexibility.　This　study　employs　disordered　structures,　utilizing　their　randomness　and　diversity,　to　optimize　and　enhance　the　performance　of　periodic　structure　metamaterial　absorbers.　Building　upon　a　well-designed　periodic　perfect　absorption　structure,　a　uniform　distribution　function　is　introduced　to　analyze　the　effects　of　positional　and　size　disorder　on　the　absorptive　properties　of　the　metamaterial.　The　mechanisms　of　the　disorder　are　further　investigated　through　simulation　analysis.　Subsequently,　an　innovative　approach　based　on　disorder　engineering　for　broadband　enhancement　of　metamaterial　absorbers　is　proposed.　Numerical　simulation　results　and　experimental　validations　demonstrate　that　absorbers　constructed　using　this　method　significantly　broaden　the　absorption　bandwidth　while　maintaining　excellent　angular　and　polarization　stability.　This　research　not　only　offers　a　new　method　for　the　design　and　performance　optimization　of　metamaterial　absorbers　but　also　provides　a　theoretical　foundation　for　the　development　of　metamaterial　self-assembly　techniques.　©　2024　Optica　Publishing　Group　under　the　terms　of　the　Optica　Open　Access　Publishing　Agreement.
