The coupling between the HDG and the BI equations is realized using the numerical flux operating on the equivalent current and the global unknown of the HDG. This approach yields sparse coupling matrices upon discretization. Inclusion of the BI equation ensures that the only error in enforcing the radiation conditions is the discretization. However, the discretization of this equation yields a dense matrix, whi","authors_text":"Hakan Bagci, Jun Hu, Liang Chen, Ming Dong, Ran Zhao","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CE","submitted_at":"2022-10-06T13:18:35Z","title":"A Coupled Hybridizable Discontinuous Galerkin and Boundary Integral Method for Analyzing Electromagnetic Scattering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2210.04892","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":"sha256:0883270d7e74b5161541cffc9043d21506a9b08db8c50b938f40e40e1daa676b","target":"record","created_at":"2026-07-05T06:21:54Z","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":"c1fdaca39b0d2590c106ef9c32e69afbb450815326598c2fa428a6705da9ffcb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CE","submitted_at":"2022-10-06T13:18:35Z","title_canon_sha256":"0f7ad536e0cc11ae58c09e524585c710d678c9d72da935b46dce4b712db568ed"},"schema_version":"1.0","source":{"id":"2210.04892","kind":"arxiv","version":3}},"canonical_sha256":"c43e31be8ab3b3acd6e1647e62a42d9a8c808a51da4b5aeb310271a3e5409a02","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c43e31be8ab3b3acd6e1647e62a42d9a8c808a51da4b5aeb310271a3e5409a02","first_computed_at":"2026-07-05T06:21:54.009596Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:21:54.009596Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8QCXc57wOcylIzw9ON+YV+DmYf3d5WH1DJI1ZdczqI5HTeClAubvfKRvgFwkFdxlVuetAzU4hkTLJgBy1sbVBw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:21:54.010047Z","signed_message":"canonical_sha256_bytes"},"source_id":"2210.04892","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0883270d7e74b5161541cffc9043d21506a9b08db8c50b938f40e40e1daa676b","sha256:c22e339b41417f2662a7ace2df567af66855c4379787aaec24469574d2d68b35"],"state_sha256":"115c2969fcec97fbbe5a78891350b40c27316f37d5a8efd876f9358569538de6"}
