Abstract
We study theoretically light focusing at subwavelength scale inside a disordered strongly scattering open medium. We show that broadband time reversal at a single point antenna, in conjunction with near-field interactions and multiple scattering, produces spatial focusing with a quality comparable to that obtained in an ideal closed cavity. This gives new perspectives for super-resolved optical imaging and coherent control of single nanosources or absorbers in complex media.
