The existence conditions of these resonances are topologically related to the zeros of the high-k characteristic function h(k)=0 of bulk bianisotropic materials and Durach","authors_text":"Felix Williamson, Franchescia Smith, Jacob Adams, Maxim Durach, Pooja Bhatt, Rebecka Moreno, Tonilynn Holtz","cross_cats":["cond-mat.mes-hall","cond-mat.mtrl-sci"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2021-11-06T03:30:49Z","title":"On Fresnel-Airy Equations, Fabry-Perot Resonances and Surface Electromagnetic Waves in Arbitrary Bianisotropic Metamaterials, including with Multi-Hyperbolic Fresnel Wave Surfaces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2111.03791","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":"sha256:26cf55782386fd15d21d42f600fd1793e8a88588f1c36847e379763d1245e60d","target":"record","created_at":"2026-07-05T03:29:31Z","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":"80787b8c1657b108158a6b46247bd16321827985c36d49e29588622798fa7703","cross_cats_sorted":["cond-mat.mes-hall","cond-mat.mtrl-sci"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2021-11-06T03:30:49Z","title_canon_sha256":"b9027cb1c52493072e1762181420e0017b7cedce5d00a332e7931ecbb2a44598"},"schema_version":"1.0","source":{"id":"2111.03791","kind":"arxiv","version":1}},"canonical_sha256":"d62399050556a839b48073ad8ca988a825036710b9fad185085b1059f5be5821","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d62399050556a839b48073ad8ca988a825036710b9fad185085b1059f5be5821","first_computed_at":"2026-07-05T03:29:31.748283Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:29:31.748283Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qNIpZ88qkmqxEczc/k6Ye1x4Exw52FWciXwaGJJyg2x/r1N6A/LnU08E+SSZcovh5yvDdaEwuLUaQzHNrL8tDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:29:31.748727Z","signed_message":"canonical_sha256_bytes"},"source_id":"2111.03791","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26cf55782386fd15d21d42f600fd1793e8a88588f1c36847e379763d1245e60d","sha256:d8542fcaebf104d70d8dcd05f5e6dcc24a1134bf4c8d8e30226e59a137064f9d"],"state_sha256":"1b11048a9f8c50cf71d8e5dcc648601d0c83b1cc1adefab649dcc49723c5d4f0"}
