The interaction of non-monochromatic radiation with two types of arrayscomprising both plasmonic and dielectric nanoparticles has been studied indetail. We have shown that dielectric nanoparticle arrays provide a completeselective reflection of an incident plane wave within a narrow spectral line ofcollective lattice resonance with a Q-factor of $10^3$ or larger, whereasplasmonic refractory TiN and chemically stable Au nanoparticle arraysdemonstrated high-Q resonances with moderate reflectivity. The spectralposition of these resonance lines is determined by the lattice period, as wellas the size, shape and material composition of the particles. Moreover, thearrays, with fixed dimensional parameters make it possible to fine-tune theposition of a selected resonant spectral line by tilting the array relative tothe direction of the incident radiation. These effects provide possibilitiesfor engineering of novel selective tunable optical high-Q filters in a widerange of wavelengths: from visible to middle IR. Several highly refractivedielectric nanoparticle materials with low absorption are proposed for variousspectral ranges, such as LiNbO$_3$, TiO$_2$, GaAs, Si, and Ge.
