We show hyperbolic phase distributions cause spherical aberration from mismatched light propagation geometry and unrealistic phase assumptions. By analyzing metalens fundamentals via isophase surfaces, we develop a spherical phase profile based on spherical wavefront theory. This method prevents spherical aberration, essential for wide-aperture metalenses. Simulations prove superior focusing: spherical phase reduces FWHM by 7.3% and increases peak intensity by 20.4% versus hyperbolic desi","authors_text":"Lei Yang, Xiaohui Yang, Xinhui Lu, Yu Guo","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2025-06-05T16:43:12Z","title":"Spherical Phase Metalenses: Intrinsic Suppression of Spherical Aberration via Equiphase Surface Modulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.05228","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:f4b506830243fc5ef164a6cbef748d0a42da27321ed48ba86e4cfc6f4000ef09","target":"record","created_at":"2026-05-28T02:04:40Z","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":"6b6918e994b5df50dc3b83258a94348c066afab4668f2525ea95babcb2ce4e2a","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2025-06-05T16:43:12Z","title_canon_sha256":"aea26eb91bb6beeead0f2a351fc11e62c03986f63eac68c22641f677face8646"},"schema_version":"1.0","source":{"id":"2506.05228","kind":"arxiv","version":2}},"canonical_sha256":"2ad6f85ba50bc9df21d4eb48f8f2b405ab548af86035cce82e4cfc3493acfdc5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ad6f85ba50bc9df21d4eb48f8f2b405ab548af86035cce82e4cfc3493acfdc5","first_computed_at":"2026-05-28T02:04:40.988586Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-28T02:04:40.988586Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4ARCJPerMvRrW61qC35olCVLd96fQGBlxEOYj0A70+DsB1bFPOh3Qobyu6hWpsHCuwbXhJqA1uMPYVbRoWe4Ag==","signature_status":"signed_v1","signed_at":"2026-05-28T02:04:40.989112Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.05228","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f4b506830243fc5ef164a6cbef748d0a42da27321ed48ba86e4cfc6f4000ef09","sha256:872642475342f2e031cb79305c127914d68604a1853ffe2000ee415b7d51a24c"],"state_sha256":"7c8beb82d66e32fac2e00f935ec441fc2eb2a719a47cb404ac3a2e5c6ea80695"}
