In contrast to previous publications, we assumed that an intrinsic surface impedance due to a finite electric conductivity of the metal can be of the same order as the roughness-induced impedance. We then applied our results to the analysis of a long-standing problem of the discrepancy between the experimental data on the propagation of surface waves in the terahertz range of frequencies and the classical Drude theory.","authors_text":"Gennady Stupakov, Igor Kotelnikov","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2016-08-10T09:19:15Z","title":"Dispersion Relation of a Surface Wave at a Rough Metal-Air Interface"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.03101","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":"sha256:3f45ca2c5db6081bc893cdfb5971fd060a939dbfcf248ab6c30eb0d61f0a025b","target":"record","created_at":"2026-05-18T00:55:45Z","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":"4e2c737915c0a8ff43eb9d3f7f1d4cb8a7f1a430c802b0d3aae8b5ca6fdcb03e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2016-08-10T09:19:15Z","title_canon_sha256":"caeb0bb66551de0691368f1d548a4417f55e008c1047ae109f17d2a4f0c89c44"},"schema_version":"1.0","source":{"id":"1608.03101","kind":"arxiv","version":1}},"canonical_sha256":"0fb158bb73d5b05c5586de1035860089ab203eeebfab92d4a1b65844add24ad9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0fb158bb73d5b05c5586de1035860089ab203eeebfab92d4a1b65844add24ad9","first_computed_at":"2026-05-18T00:55:45.570476Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:55:45.570476Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"do8qVy5O4Y8XEzrfY56EFr/CRlZORez8SexHS/XBdJCZmiASt54nakuJRwFhO/WTn9mYAjCwKCc7YSdsA7nkDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:55:45.570928Z","signed_message":"canonical_sha256_bytes"},"source_id":"1608.03101","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3f45ca2c5db6081bc893cdfb5971fd060a939dbfcf248ab6c30eb0d61f0a025b","sha256:48864286c293dac8128737cf3a548a456bc658066ea83abfd26929cd1b00b56c"],"state_sha256":"c93737b7cdb88578a5a8ed1f878420f68e9e36519ef05cf507c271263f466071"}
