Abstract
Methods of manufacturing a volumetric continuous gradient complex dielectric element with drop-on-demand techniques, such as inkjet printing, by calculating spatial placement of nanocomposite-ink droplets are disclosed. The methods comprise determining or having a multi-dimensional gradient profile representing a volumetric gradient complex dielectric element. Providing or having a plurality of nanocomposite-inks, at least one of the nanocomposite-inks having a curable organic-matrix and a concentration of nanoparticles dispersed within to print the volumetric continuous gradient complex dielectric device. A print mask is determined in one-, two-, or three-dimensions that reconstructs the multi-dimensional gradient profile as a discretized pattern based on the material properties of the plurality of nanocomposite-inks and properties of a printing apparatus. A spatial or spatio-temporal print schedule is determined that results in an at least approximate reproduction of the gradient profile when printed with the printing apparatus.
