Abstract

The invention discloses a low loss electromagnetic induced transparency all dielectric meta-material structure insensitive to polarization and incoming angles and belongs to the technical field of meta-material. A cubic plane of a first cube of the low loss electromagnetic induced transparency all dielectric meta-material structure is provided with a first square air hole and a second square air hole along the X-axis direction and the Y-axis direction of a spatial rectangular coordinate system respectively. The gravity center of each of the first square air hole and the second square air holecoincides with the gravity center of the first cube. A cubic plane of a second cube is provided with a third square air hole and a fourth square air hole along the X-axis direction and the Y-axis direction of the spatial rectangular coordinate system respectively. The gravity center of each of the third square air hole and the fourth square air hole coincides with the gravity center of the first cube. The gap between the second cube and the first cube is 1 mm. When the two resonators are combined into the meta-material unit, due to near field coupling effect in Mie electromagnetic resonance, aims of low loss and high wave transmission rate can be realized.

Description

technical field [0001] The invention belongs to the technical field of metamaterials, and in particular relates to a low-loss electromagnetic induction transparent all-dielectric metamaterial structure which is insensitive to polarization and incident angle. Background technique [0002] Electromagnetically induced transparency is an important quantum optical effect. When the pump light and the probe light act together on the atom, quantum destructive interference is formed between the excitation paths of the atom, resulting in a decrease in light absorption at the atomic resonance frequency, thereby Creates a distinct transparent window in the transmission spectrum. This transparency effect is usually accompanied by very steep phase dispersion, resulting in many important applications, such as slow light propagation, optical delay, and optical storage, etc. However, the practical application of the electromagnetically induced transparency effect is limited by material sele...
