Existing analytical models, however, often rely on isotropic radiation assumptions and simplified couplingefficiency settings, which may overlook two practical design factors: the geometry-dependent radiation pattern of each PA and the sequential extraction of guided power along the waveguide. In this paper, we propose a measured-radiation-pattern-aware PA framework that incorporates an externally obtained radiation pattern, waveguide attenuation, and coupling-dep","authors_text":"Ebrahim Bedeer, Hao Feng, Hui Yang, Ming Zeng, Nian Xia, Yulei Wang","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2026-06-25T00:11:26Z","title":"Measured-Pattern-Aware Pinching-Antenna Systems With Coupling-Efficiency Optimization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.26471","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":"sha256:092b0340ca8b7975ade71e07a119d2894df563ee63644e1183f0ccb0e4e7b9d1","target":"record","created_at":"2026-06-26T01:15:32Z","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":"fd131e088f1554b0419b9d067255fea811b37d2bcc3b863b0c92b4400d32d0e3","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2026-06-25T00:11:26Z","title_canon_sha256":"7f06e20066f5da7eae8285be17c5cb66f33706623a34182b325a71f0995af326"},"schema_version":"1.0","source":{"id":"2606.26471","kind":"arxiv","version":1}},"canonical_sha256":"43969413aa4f5f47bfceef552d09cf11e5149d86f0d847f27a8360bb42f3d86b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"43969413aa4f5f47bfceef552d09cf11e5149d86f0d847f27a8360bb42f3d86b","first_computed_at":"2026-06-26T01:15:32.146408Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-26T01:15:32.146408Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HlSkZsdgWuE/MEzGIdoPfdkUAW3HGJHhOrUBCXWk9n4sitHAJTmm+FU1RgmMnSZVLeYW5v+Cn6WEj2lqMJckDA==","signature_status":"signed_v1","signed_at":"2026-06-26T01:15:32.146875Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.26471","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:092b0340ca8b7975ade71e07a119d2894df563ee63644e1183f0ccb0e4e7b9d1","sha256:e2932d9a7a108ce46c80902e1ebe59034f0ec7a458cebd840970c29fcc53b7a0"],"state_sha256":"087e5872bc66f94f3ef278d3ffede99c59f0e819bd2c6b1f888b9bcc6624283b"}
