The LLM proposes how to tweak a design's parameters, a cheap predictive model screens the resulting candidates, and only the most promising ones get run through full-wave electromagnetic simulation. Designs that pass physical-validity checks feed back into the search, and lessons learned get distilled into reusable text skills for future tasks. On a held-out benchmark of 36 absorber-design tasks, AbsorbEvo hit a 79.17% success rate, versus 25.00% for a generic AI agent and 12.50% for random search, with notably better coverage of the target performance too.\n\nThat gap matters because absorber design has long been a slow, expertise-gated process, requiring fluency in electromagnetic theory, materials science, and simulation tooling most engineers don't have. Folding that expertise into an agent that takes natural-language specs could shrink a multi-week optimization cycle into something closer to a conversation, and the same pipeline looks adaptable to other inverse-design problems like antennas or metamaterials.\n\nStill, this is one lab's benchmark built on its own tasks, not a product tested against real-world fabrication constraints, so treat the 79% success rate as a promising lab result rather than proof the hardware works outside a simulator.","[\"ai agents\",\"inverse design\",\"materials science\",\"microwave absorbers\"]","2026-10-02T04:00:00.000Z","2026-10-02T22:23:51.617Z","2026-10-02T22:23:56.628Z","published",null,[],"ai",[26,27,28,29],"ai agents","inverse design","materials science","microwave absorbers",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.01119",0,{"sections":36},[37,40,44,48,53,57,61,66,71,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5886,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",835,{"name":45,"slug":46,"count":47,"latest_published_at":18},"Policy","policy",438,{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",317,"2026-10-01T22:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":18},"Hardware","hardware",199,{"name":58,"slug":59,"count":60,"latest_published_at":18},"Science","science",171,{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",155,"2026-10-01T19:54:10.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Dev Tools","dev-tools",96,"2026-10-01T16:57:03.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",93,"2026-09-30T21:41:11.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",90,"2026-10-01T21:55:22.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
