Our results reveal the emergence of a wavefield which resembles that of a shadow boundary but has a maximum amplitude along the tangent at the inflection point. date: 2024-02-01 date_type: published publisher: Elsevier BV official_url: http://dx.doi.org/10.1016/j.wavemoti.2023.103257 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2135288 doi: 10.1016/j.wavemoti.2023.103257 lyricists_name: Gibbs, Andrew lyricists_name: Hewett, David lyricists_id: AGIBB63 lyricists_id: DHEWE35 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Wave Motion volume: 125 article_number: 103257 citation: Ockendon, JR; Ockendon, H; Tew, RH; Hewett, DP; Gibbs, A; (2024) A caustic terminating at an inflection point.
