Experimental and theoretical data on the study of resonance effects in electromagnetic spectra of various photonic structures are reviewed presented. We briefly remind the history of the formation of scientific fields related to photonic crystals and metamaterials, which were initially considered as two different classes of artificial objects, and recently more often analyzed from general positions. Our special attention is paid to the phase transition between photonic crystal and metamaterial regimes, which is accompanied by the appearance of a negative magnetic susceptibility in a purely dielectric two-dimensional structure. The main mechanisms for the formation of resonant processes associated with extended (i.e., non-local) Bragg resonances in photonic crystals and local resonances on individual structural elements of metamaterials are considered. We discussed in details the electromagnetic properties of weakly absorbing dielectric particles with a high refractive index, which, in addition to electrical resonances, possess intensive magnetic Mie resonances. The relevance of this direction is determined by an intensive research aimed at creating the element base of photonics.
