In particular, Floquet systems with a periodic time modulation are currently of considerable interest. Here, we demonstrate how the scattering properties of a finite Floquet medium can be correctly described by a static Floquet scattering matrix, which satisfies a pseudounitary relation. This algebraic property is a consequence of the conservation of wave action for which we formulate here a continuity equation. Using this Floquet scattering matrix, we further de","authors_text":"David Globosits, Jakob H\\\"upfl, Stefan Rotter","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2024-03-28T11:02:34Z","title":"Pseudounitary Floquet scattering matrix for wave-front shaping in time-periodic photonic media"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2403.19311","kind":"arxiv","version":2},"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":"sha256:04ac67bba6cc882fcd2661aa489756aa2265ba94dc5c565f63a2725c3bf8f6ca","target":"record","created_at":"2026-07-05T09:37:52Z","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":"d74ff509ad574e3be2cd98c0156db28735772849848038c2aa7ffb8ccae80a83","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2024-03-28T11:02:34Z","title_canon_sha256":"d36e5e6ac1e53a405db1d3e9893c501fc1432153aff01902f417fc30a428ba0f"},"schema_version":"1.0","source":{"id":"2403.19311","kind":"arxiv","version":2}},"canonical_sha256":"3cf5583b0ce9d3b14a83f0ecc420be4fcc830902479e5efdf84e4aaf27b4d4c3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3cf5583b0ce9d3b14a83f0ecc420be4fcc830902479e5efdf84e4aaf27b4d4c3","first_computed_at":"2026-07-05T09:37:52.594122Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:37:52.594122Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KI2yfxlKoV7qRV7joSKXUQwEIsi70GnazIxc/K+hb0aQ0OnPWjLPVWurbJ5Dl9LgHkz8yXLSnv3xTmNQ+jSmAw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:37:52.594714Z","signed_message":"canonical_sha256_bytes"},"source_id":"2403.19311","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:04ac67bba6cc882fcd2661aa489756aa2265ba94dc5c565f63a2725c3bf8f6ca","sha256:64c4d7fa62e9f30fde405c7ea2917e3a52e17bfa5cc5a45b9229ab3430e14c82"],"state_sha256":"6af27b69c64015a992f6702a4d1d9473c280c96bebc2aa46bb1edd16b3ac6edf"}
