タイトル:二次元ユークリッド空間内の一次元的周期構造による散乱共鳴現象の解析
アブストラクト:周期構造は光や音といった波動の散乱共鳴を制御する目的でメタマテリアルのデザインに取り入れられており,生じる特異な性質は理論と応用の両面で注目されている.本発表では,二次元ユークリッド空間内に一次元的に並んだ周期構造による散乱共鳴現象の解析について,発表者のこれまでの研究成果を交えて紹介する.加えて,周期構造におけるBIC(連続スペクトル中の束縛状態)の一種であるDirichlet trapped modeの存在について発表者が得た最新の成果を紹介する.

Title: Analysis of Scattering Resonance Phenomena Induced by One-Dimensional Periodic Structures in Two-Dimensional Euclidean Space
Abstract: Periodic structures are incorporated into metamaterial designs to control the scattering resonances of waves such as light and sound, and the resulting unique properties have attracted significant attention from both theoretical and applied perspectives. In this presentation, we introduce an analysis of scattering resonance phenomena caused by one-dimensional periodic structures in two-dimensional Euclidean space, alongside the presenter's previous research findings. Furthermore, we present our latest results concerning the existence of Dirichlet trapped modes, a type of Bound State in the Continuum (BIC), within periodic structures.
