Abstract

A method of inkjet printing a gradient dielectric element in a deposition and photo-polymerization process. The method comprises: providing a plurality of complex-dielectric-inks that are inkjet printable including a nanocomposite-ink with an organic-matrix and a nanoparticle filler dispersed within. The plurality of complex-dielectric-inks have a first complex-dielectric-ink having a first photoinitiator and a second complex-dielectric-ink with a second photoinitiator. The first and second complex-dielectric-ink have different wavelength selective photo-polymerization absorption bands such that spectrally discrete exposure results in different degrees of polymerization of the first and second complex-dielectric-ink. The method further comprises providing an optical source to polymerize the complex-dielectric-inks, depositing droplets of the plurality of complex-dielectric-ink and curing the plurality of complex-dielectric-inks, wherein deposition of the plurality of layers result in a volumetric nanoparticle concentration gradient.
