Maxwell equations for multi-layer dielectric structure realizing spherical DR screening by 1-D photonic crystal has been solved. Received data are allowing to assert that lattice forming on the DR surface can adduce to significant increasing of it Q-factor for resonances with large values of radial indexes. It's noting a possibility significant frequency spectrum depression in comparison to other resonance types.</p> ER -
