Traditional methods, such as gradient-based optimization, and recent generative deep-learning approaches often rely on binary pixel-based representations, which introduce jagged edges that hinder finite element (FE) simulations and 3D printing. To overcome these challenges, we propose an inverse design framework that utilizes a signed distance function (SDF) representation combined with a conditional","authors_text":"Diab Abueidda, Hadi Meidani, Philippe Geubelle, Qibang Liu, Seid Koric","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-04-01T21:17:41Z","title":"Towards Signed Distance Function based Metamaterial Design: Neural Operator Transformer for Forward Prediction and Diffusion Model for Inverse Design"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.01195","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0359fdb686999b5d16070180305765d571f3f2dbfedff9050c0014036b49ca56","target":"record","created_at":"2026-07-05T11:10:55Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"03c92da89c03321a53860d9d2a78ebf121ec3d1fa81d42894a85e973cfc3ea8e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-04-01T21:17:41Z","title_canon_sha256":"6bc57933693c23c407cf4b59caed873fa867233420849447ee3e0747c5da841a"},"schema_version":"1.0","source":{"id":"2504.01195","kind":"arxiv","version":3}},"canonical_sha256":"88d8f881de9a56282279681fdd260b1bce73bc1c09b3004d213fc64deee0a199","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"88d8f881de9a56282279681fdd260b1bce73bc1c09b3004d213fc64deee0a199","first_computed_at":"2026-07-05T11:10:55.261729Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:10:55.261729Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3Ha/cOm69KoWFpaMnQPyG3B9AQFXhCJU34F/+RIaU3qem/x+TRWVn0mZzg1SULH8DgdZKEoQsX9DOfbg3btTAg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:10:55.262199Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.01195","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0359fdb686999b5d16070180305765d571f3f2dbfedff9050c0014036b49ca56","sha256:8c9ed0e403cfe5cdcdf0697d079f9d37b2260a77b499a6f5f2459a1ae1160e28"],"state_sha256":"4b3d241ddb88f1fd67da80866a0d084763beb70e12804bde500ee75532dca122"}
