Microwave frequency band electromagnetic induced transparency structure

ActiveCN117096617BMature manufacturing technologyEasy to manufactureAntennasWave detectionTransmittance
The electromagnetic induced transparency structure of microwave frequency band of the present application belongs to the technical field of electromagnetic wave detection and sensor device, which is composed of hollow metal rectangle (1), solid metal rectangle (2) and dielectric layer (3). The hollow metal rectangle (1) and the solid metal rectangle (2) are arranged periodically in two directions perpendicular to each other on the same surface of the dielectric layer (3), the hollow metal rectangle (1) and the solid metal rectangle (2) are different by 45 degrees, and the midpoint of each side of the solid metal rectangle (1) is just in contact with a vertex of the hollow metal rectangle (2). The structure of the present application can realize electromagnetic induced transparency effect, the transmittance reaches more than 90%, and the polarization direction of the incident light does not affect the structure, which has the advantage of being insensitive to the incident angle, and the selected materials are mature in preparation technology and easy to manufacture.
