Electromagnetic properties of dielectric multilayer periodic structures with inclusions of gain medium

Resonant enhancement of transmission and reflection of a plane electromagnetic wave incident on a multilayer all-dielectric periodic structures is studied theoretically. Each layer can be a square lattice of cylinders embedded in a dielectric slab or a uniform slab. A defect layer and gain medium inclusions has been designed specifically to obtain a high-density mode. The numerical investigation is performed for a near infrared wavelength range. Spectral characteristics, 3D vector plots and maps for electromagnetic fields in the structures with dissipative losses are presented.
