Graded photonic crystals curve the flow of light: An experimental demonstration by the mirage effect Auteur(s): Akmansoy Eric, Centeno Emmanuel, Vynck Kevin, Cassagne D., Lourtioz Jean-Michel (Article) Publié: Applied Physics Letters, vol. 92 p.133501 (2008) Ref HAL: hal-00437947_v1 DOI: 10.1063/1.2901684 WoS: 000254669900098 Exporter : BibTex | endNote 55 Citations Résumé: We report the experimental demonstration of a beam curvature in graded photonic crystals via a spectacular mirage effect. A two-dimensional structure of metallic rods is constructed to produce this effect in the microwave domain near 10 GHz. Experimental results are in excellent agreement with theoretical predictions, thus, proving the versatility of graded photonic crystals in view of their integration in future photonic circuits.
