Thin layers of all-dielectric metamaterials based on TiO2
spherical particle resonators are investigated. A new method
based on spray-drying of dissolved nanoparticles is used in
the fabrication process. Spectral footprints of electric and
magnetic dipoles are reported numerically and through
experimental tests. It is a promising step for the construction of novel three-dimensional isotropic metamaterials exhibiting desired electromagnetic properties for terahertz applications.
