We provide the first experimental evidence of sharp, resonant extinction in freestanding arrays of non-resonant nanorods. Nearly perfect optical extinction and strong absorption enhancement is shown for transparent and absorbing material, respectively. The results can be fully explained by a coherent multiple scattering model in periodic arrays of subwavelength nanorods.
