Unique features and applications of time-varying metamate-rials are highlighted including independent control over phase and amplitude of harmonics, dispersionless wavefront engineering, spatiotemporal manipulation of light and nonreciprocal response.

Recently, an all-dielectric perturbed honeycomb topological photonic crystal has attracted attention due to its simplicity of fabrication. However, its edge states intrinsically suffer from back-reflection due to the symmetry breaking at the interface. Here, we propose an all-dielectric reciprocal photonic topological insulator based on the geometry of a kagome lattice in which the topological edge modes do not undergo back-reflection for termination along the $Gamma - K$ direction. In contrast to the perturbed honeycomb, the edge modes in our kagome-based structure are below the light cone leading to improved vertical mode confinement.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120961077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
