We consider a problem of obtaining a complete photonic bandgap in all-dielectric metamaterial made of low-permittivity dielectric. A distributed three-dimensional quasiperiodic structures in which the number of Bragg peaks and their position in reciprocal space can be arbitrarily tuned is considered as a solution to this problem. An analytical estimation of such structure is presented as well as the results of a numerical simulation of a finite structure in CST Microwave Studio. An experimental sample of quasicrystal was fabricated by means of 3D-printing, and the results of the experimental study are in good agreement with the theoretical results. Also the speaker will present a short review of his other recent scientific results.
