Around the time when I started my PhD studies, a new, rather brilliant idea was presented in two (at least?) papers which dealt with the response of submicron-sized high-refractive index (in particular – silicon) nanoparticles which exhibited very strong magnetic resonances:
“Optical response features of Si-nanoparticle arrays”, Andrey B Evlyukhin, Carsten Reinhardt, Andreas Seidel, Boris S Luk’yanchuk, and Boris N Chichkov, Physical Review B 82, 045404 (2016).
“Strong magnetic response of submicron Silicon particles in the infrared”, Aitzol Garcia-Etxarri, R Gómez-Medina, Luis S Froufe-Perez, C López, L Chantada, F Scheffold, J Aizpurua, M Nieto-Vesperinas, JJ Sáenz, Optics Express 19, 4815 (2011).
Since, the number of papers devoted to translating plasmonic designs into dielectric systems, and proposing novel effects which would benefit from the strong magnetic response, blew up. I have contributed to this development, co-authoring the following publications:
“Isotropically polarized speckle patterns“, Mikołaj K. Schmidt, Javier Aizpurua, Xavier Zambrana-Puyalto, Xavier Vidal, Gabriel Molina-Terriza, and Juan José Sáenz, Physical Review Letters 114, 113902 (2015).
here we discuss how the polarization of light scattered in random solution of dielectric particles can be preserved; it doesn’t seem like a complex effect, but can have tremendous implications
“Antenna resonances in low aspect ratio semiconductor nanowires”, Daniel J. Traviss, Mikołaj K. Schmidt, Javier Aizpurua, and Otto L. Muskens, Optics Express 23, 22771 (2015).
here we attempt to unravel the optical response of dielectric nanowires; we propose a description which mixes the Mie theory and the concept of Fabry-Perot resonators
“Electromagnetic Resonances of Silicon Nanoparticle Dimers in the Visible“, Urs Zywietz, Mikołaj K. Schmidt, Andrey B. Evlyukhin, Carsten Reinhardt, Javier Aizpurua, and Boris N. Chichkov, ACS Photonics 2, 913 (2015).
here we expand the hybridization theory to describe the response of dimers of dielectric nanoparticles and understand the experimental results
“Low-loss electric and magnetic field-enhanced spectroscopy with subwavelength silicon dimers”, Pablo Albella, Mohammed Ameen Poyli, Mikołaj K. Schmidt, Stefan A. Maier, Fernando Moreno, Juan J. Sáenz, and Javier Aizpurua, Journal of Physics Chemistry C 117, 13573 (2013).
here we propose (to our best knowledge – for the first time) a simple framework to describe the response of dielectric dimers
“Dielectric antennas – a suitable platform for controlling magnetic dipolar emission”, Mikołaj K. Schmidt, Ruben Esteban, Juan J. Saenz, Irene Suarez-Lacalle, Sebastian Mackowski, and Javier Aizpurua, Optics Express 20, 13636 (2012) + errata.
here we expand the analytical framework for calculating the rate enhancement for the spontaneous emission from electric dipoles to the magnetic dipoles; we further analyze the performance of dielectric particles as magnetic antennas
