We numerically investigate the resonance properties of the reflective metasurface, which is a planar, two-direction lattice of pairs of dielectric bars placed on a metal substrate. The structure is designed in such a way and with such sizes that in its subwavelength mode the first few lowest frequency resonances fall within the far infrared wavelength range. To study the physical processes in the...
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...
We investigate the resonant enhancement of transmission and reflection of a plane electromagnetic wave incident on a multilayer three-dimensional fully dielectric photonic crystal in which a defect layer with excited medium inclusions has been designed specifically to obtain a high-density mode. The numerical investigation is performed for a near infrared wavelength range. Comparison of transmission...
