Abstract
The properties of electromagnetic field surface states in globular photonic crystals are analyzed using numerical solution of Maxwell equations by the finite-difference method. The spatial distributions of the optical radiation intensity near the photonic crystal surface are obtained. A significant redistribution of the field strength in the crystal bulk, accompanied by the appearance of high-intensity local peaks, is shown. It was found that the maximum local intensity of radiation is observed when the exciting radiation wavelength coincides with the crystal band gap position. In this case, the average electromagnetic wave intensity rapidly decreases from the surface to the photonic crystal depth.
