For example, the angles of incidence and diffraction of a grating are locked through the grating momentum determined by the grating period. Other diffractive devices, including conventional metasurfaces, have a similar angular behavior due to the fixed locations of the Fresnel zone boundaries and the weak angular sensitivity of the meta-atoms. To alter this fundamental property, we introduce angle-multiplexed metasurfaces, composed of reflective high-contrast dielectric U-shaped meta-atoms, whose response under ill","authors_text":"Amir Arbabi, Andrei Faraon, Ehsan Arbabi, MohammadSadegh Faraji-Dana, Seyedeh Mahsa Kamali, Yu Horie","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-11-07T02:54:42Z","title":"Angle-multiplexed metasurfaces: encoding independent wavefronts in a single metasurface under different illumination angles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.02265","kind":"arxiv","version":1},"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":"sha256:24c7018a822645c74485a28f501a518dd9315c15ea9c6965ec635efe4c649d79","target":"record","created_at":"2026-05-18T00:31:08Z","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":"c5dfd6488de4552a2f6b9d131658baa1661b09cf72f97d37bd8c9165bfcc2052","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-11-07T02:54:42Z","title_canon_sha256":"bcaaa5de1cafca22e9db3163b6f4a8c8f6655e46a886665750cc4be4ce1685ae"},"schema_version":"1.0","source":{"id":"1711.02265","kind":"arxiv","version":1}},"canonical_sha256":"5ffbda64fdbc6e9ca0d4dd8cd0c9bea4867edcd76138382de2983fca04ca2efc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5ffbda64fdbc6e9ca0d4dd8cd0c9bea4867edcd76138382de2983fca04ca2efc","first_computed_at":"2026-05-18T00:31:08.389417Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:31:08.389417Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IvctY0yUUo9uJQMiDggL+SJwNGnClTVYRZGPCkL/vhL3pW2oZaGrmFRFlqsQeDi4yYjwoG326JhxWja4NLl3Bg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:31:08.389951Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.02265","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:24c7018a822645c74485a28f501a518dd9315c15ea9c6965ec635efe4c649d79","sha256:4425878d6e302dc44e2cc050e3960fad4d3d3009bf8149aea64997c314dceb91"],"state_sha256":"e0f082dcfe17b56184e0420ac0ee8635cb1f9c87b0e9b2f2b12e59ad130eeb9f"}
