These metasurfaces manipulate the electromagnetic (EM) wave by introducing abrupt phase change, which is strongly dependent on the polarization state of incident EM wave and can be interpreted by geometric phase. Hence, the conventional bulk devices that based on the accumulated phase change along the optical path can be avoided. date: 2018-03 date_type: published publisher: MDPI official_url: https://doi.org/10.3390/app8030362 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Review verified: verified_manual elements_id: 1569132 doi: 10.3390/app8030362 lyricists_name: Sha, Wei lyricists_id: WSHAX37 actors_name: Waragoda Vitharana, Nimal actors_id: NWARR44 actors_role: owner full_text_status: public publication: Applied Sciences volume: 8 number: 3 article_number: 362 pages: 18 issn: 2076-3417 citation: Chen, MLN; Jiang, LJ; Sha, WEI; (2018) Orbital Angular Momentum Generation and Detection by Geometric-Phase Based Metasurfaces.
