The technique takes into account the surface conductivity of graphene which allows the correct calculation of its dispersive response for arbitrarily polarized incident waves interacting with the graphene.The developed technique is verified for a planar graphene sheet configuration against the exact analytical solution. Based on the same test case scenario, we also show that the subcell technique demonstrates a superior accuracy and numerical efficiency with ","authors_text":"Ilya Valuev, Maria Bogdanova, Oleg Kotov, Sergei Belousov, Yurii Lozovik","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-11-23T17:53:38Z","title":"FDTD subcell graphene model beyond the thin-film approximation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.07903","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:ec5820eda9f532f399b7bc6ad18baf225c2f2ec03e62792be37f4a8b3dfe37ad","target":"record","created_at":"2026-05-18T00:51:42Z","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":"5766834887efb09a63e62667368310291f927ef1938398bf8aa062877f2dc843","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-11-23T17:53:38Z","title_canon_sha256":"6f4c60253f32b92a584645522a16d95071f261aec11c5029aa27071d005219fc"},"schema_version":"1.0","source":{"id":"1611.07903","kind":"arxiv","version":1}},"canonical_sha256":"cdc9060e70a4a09f2ff3b8a107190e54c496d1fce9ab7c0a64a4a8c71d42e3c9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cdc9060e70a4a09f2ff3b8a107190e54c496d1fce9ab7c0a64a4a8c71d42e3c9","first_computed_at":"2026-05-18T00:51:42.057275Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:51:42.057275Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VpFw5zk1USOaEF849nGooRcR7c3gqC3Y/nmyBHZvEhIjTLRMwxeFIKPRNOL48fY+PSYG48seE1dlVKCA8tqFBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:51:42.057772Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.07903","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ec5820eda9f532f399b7bc6ad18baf225c2f2ec03e62792be37f4a8b3dfe37ad","sha256:301e77f32496448a3dd0f33b43f68978172f280a10edafde012078f592460957"],"state_sha256":"b3c64b10808abd9ff5c1c898c85a3231cb17f73d6354a6a31b88209ed57b2877"}
