Using Mie theory we address lossless dielectric spheres that were recently reported to possess a magnetodielectric response to the illuminating wave, and analyze their scattering cross section together with their zero-backwards scattering conditions. We show that there is an optimum particle refractive index (m = 2.47), which yields maximum forward scattering without backwards scattering of light.","authors_text":"Juan Jos\\'e S\\'aenz, Manuel Nieto-Vesperinas, Yan Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-07-06T04:16:52Z","title":"Dielectric spheres with maximum forward scattering and zero backscattering: A search for their material composition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1507.01325","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":"sha256:663d17ad713458fe955b6fbb0fb6ba414bce5dcdd1fcb96d787aa85e6da3d5e1","target":"record","created_at":"2026-05-18T01:27:53Z","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":"04eec4a79040b035b491afc4ff7a067b3db120885a3b04e1905a05f9465483b7","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-07-06T04:16:52Z","title_canon_sha256":"3532c0168eec53bdc668e6bcf86bcc7cd51fb34c1c3ec2ed7ef2791bc58b1a8d"},"schema_version":"1.0","source":{"id":"1507.01325","kind":"arxiv","version":2}},"canonical_sha256":"4d28968823cb05581a85041de723585314726575c20d92e0ecfcd8ad43713da0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4d28968823cb05581a85041de723585314726575c20d92e0ecfcd8ad43713da0","first_computed_at":"2026-05-18T01:27:53.900278Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:27:53.900278Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rUxDzH1XY+nodqAlRr2Dqq5SHgh+37UAk45jgI5TrBEPcbpnHLIAKykXCM2NYL0vQ318PYyI0y7vC/lVKRWsAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:27:53.901039Z","signed_message":"canonical_sha256_bytes"},"source_id":"1507.01325","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:663d17ad713458fe955b6fbb0fb6ba414bce5dcdd1fcb96d787aa85e6da3d5e1","sha256:631b537b96b48a9289c06178673edbea171591ad897ac1a407edcc72614b948a"],"state_sha256":"5096426f376ae99c8732921e22729e09616551e67efc00ad41527307ce96c55a"}
