Journal ArticleDOI
Strong magnetic response of submicron Silicon particles in the infrared
Aitzol García-Etxarri,R. Gómez-Medina,Luis S. Froufe-Pérez,Cefe López,L. Chantada,Frank Scheffold,Javier Aizpurua,Manuel Nieto-Vesperinas,Juan José Sáenz +8 more
TL;DR: This work finds that Silicon particles with index of refraction∼3.5 and radius∼200 nm present strong electric and magnetic dipolar resonances in telecom and near-infrared frequencies, without spectral overlap with quadrupolar and higher order resonances.
Journal ArticleDOI
Magnetic and electric coherence in forward- and back-scattered electromagnetic waves by a single dielectric subwavelength sphere
Jean-Michel Geffrin,Braulio García-Cámara,Braulio García-Cámara,R. Gómez-Medina,Pablo Albella,Luis S. Froufe-Pérez,Christelle Eyraud,Amelie Litman,Rodolphe Vaillon,Francisco González,Manuel Nieto-Vesperinas,Juan José Sáenz,Juan José Sáenz,Fernando Moreno +13 more
TL;DR: Experimental evidence is presented that a single low-loss dielectric subwavelength sphere of moderate refractive index radiates fields identical to those from equal amplitude crossed electric and magnetic dipoles, and indistinguishable from those of ideal magnetodielectric spheres, and these Kerker scattering conditions only depend on a/λ.
Journal ArticleDOI
Demonstration of Zero Optical Backscattering from Single Nanoparticles
Steven Person,Manish Jain,Zachary J. Lapin,Zachary J. Lapin,Juan José Sáenz,Gary W. Wicks,Lukas Novotny,Lukas Novotny +7 more
TL;DR: The first experimental demonstration of zero backscattering from nanoparticles at optical frequencies as originally discussed is presented, agreeing with calculations based on the discrete dipole approximation.
Journal ArticleDOI
Demonstration of zero optical backscattering from single nanoparticles
Steven Person,Manish Jain,Zachary J. Lapin,Zachary J. Lapin,Juan José Sáenz,Gary W. Wicks,Lukas Novotny,Lukas Novotny +7 more
TL;DR: The first experimental demonstration of zero backscattering from nanoparticles at op- tical frequencies was presented by Kerker et al. as discussed by the authors, where GaAs pillars were fabricated on a fused silica substrate and the spectrum of the backscattered radiation was measured in the wavelength range 600-1000 nm.
Journal ArticleDOI
Low-loss electric and magnetic field-enhanced spectroscopy with subwavelength silicon dimers
Pablo Albella,Pablo Albella,M. Ameen Poyli,Mikolaj K. Schmidt,Stefan A. Maier,Fernando Moreno,Juan José Sáenz,Javier Aizpurua +7 more
TL;DR: In this article, the electromagnetic behavior of the basic unit constituted by a dimer of dielectric nanoparticles made of moderately low-loss high refractive index material is explored and studied through an analytical dipole-dipole model.
