Exact time-dependent solutions of Maxwell's equations show that perfect imaging is not achievable with an electrical ideal mirror on its own, but with Maxwell's fish eye in the regime when it implements a curved geometry for full electromagnetic waves.","authors_text":"Sahar Sahebdivan, Ulf Leonhardt","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2010-07-01T06:47:49Z","title":"Perfect imaging: they don't do it with mirrors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.0078","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":"sha256:2c239852a9e63d7aa068e224a863a53f4f60501191a022806b1f81872263e000","target":"record","created_at":"2026-05-18T02:06:33Z","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":"247e1aac026a9be3b7106c1826547fc5f076431e9e079cfca724be4bb6ac4d13","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2010-07-01T06:47:49Z","title_canon_sha256":"a994ef8d611a1fcc3ffbfa91b036306cf86e6cd508c27bff76b0299ead037b15"},"schema_version":"1.0","source":{"id":"1007.0078","kind":"arxiv","version":3}},"canonical_sha256":"b4cdf1a604834dc4f3758a33642da58812c6fa92e1cd4c73c75c1ac6b50b4ca2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4cdf1a604834dc4f3758a33642da58812c6fa92e1cd4c73c75c1ac6b50b4ca2","first_computed_at":"2026-05-18T02:06:33.454447Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:06:33.454447Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zuw7b20ubbcpMnbBAwtL/psPUVNJRVrJa0MBC4FhJuOcBaAp7m49CyeyKK0qFCw2Y0s9DaxWuJwY9jOwfOerAA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:06:33.455088Z","signed_message":"canonical_sha256_bytes"},"source_id":"1007.0078","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2c239852a9e63d7aa068e224a863a53f4f60501191a022806b1f81872263e000","sha256:578d7204b9de7014bd3bdbee04583bdbf61759e8ef778b4f10e69f8bf3ac7461"],"state_sha256":"87b737bef3c355fa4dc6dd8e206132c177629c47984ff93921a59108475182d2"}
