Low-dimensional photonic crystals of the microwave

摘要

Nizkorazmernyh waveguide photonic crystal formed as a waveguide comprising elements periodically alternating in the direction of propagation of electromagnetic radiation, characterized in that the even-numbered elements of the photonic crystal formed as dielectric layers, completely filling the cross section of the waveguide, and the odd elements of the photonic crystal formed as thin metal plates partially overlapping waveguide section and forming a gap between the plate and the broad wall of the waveguide along its entire length, wherein the gap between the odd metal plates and the waveguide are located at one of the broad walls of the waveguide, and the gaps between the even metallic plates and the waveguide - in the opposite broad walls of the waveguide, the width of the gaps is the same and is in the range of up to 0,0125λ 0,0625λ , the thickness h of the dielectric layers is in the range from λ / (3) to λ / (9) somewhere length of the main wave type in the waveguide corresponding to the middle of the "forbidden" zone of the photonic crystal, - the relative permittivity of the dielectric Sgiach layers.
