Localized modes in random arrays of cylinders.
Anderson localization of classical waves in random arrays of dielectric cylinders is numerically investigated as a function of the distribution of their diameters. We show that using polydispersed resonant scatterers increases the localization length, while using identical resonant scatterers fosters Anderson localization. We discuss this collective process and link it to the effect of proximity resonances that has been studied in the case of a small number of resonant scatterers.
