Abstract

Dynamical control of metamaterials by adjusting their shape and structures has been developed to achieve desired optical functionalities and to enable modulation and selection of spectra responses. However it is still challenging to realize such a manipulation at large scale. Recently, it has been shown that the desired high (or low) symmetry metamaterials structure in solution can be self-assembled under external light stimuli. Using the this approach, we systematically investiagted the optical controlling process and report here a dynamical manipulation of magnetic properties of metamaterials. Under external laser excitations, we demonstrated that selected magnetic properties of metamaterials can be tuned with the freedom of chosen wavelength ranges. The magnetic dipole selectivity and tunability were further quantified by in situ spectral measurement.
