Abstract
The invention relates to a metamaterial phase shifter which comprises a rotatable circular waveguide and a metamaterial column which is installed inside an inner cavity of the circular waveguide. The metamaterial column comprises a plurality of metamaterial piece layers which are laminated into a whole, each metamaterial piece layer comprises a flake-like substrate and a plurality of man-made microstructures which are installed on each substrate, different parts of the same metamaterial piece layer have the same refractive index, and the refractive indexes of the metamaterial piece layers are gradually decreased from the center of the metamaterial column to two ends. According to the metamaterial phase shifter, the metamaterial column is installed inside the inner cavity of the circular waveguide, electric field distribution of the circular waveguide can be changed once the circular waveguide is rotated, and therefore phase difference of electromagnetic waves at two ends of the circular waveguide is changed. As the refractive indexes of the metamaterial piece layers are gradually decreased from the center of the metamaterial column to two ends, the size of the metamaterial phase shifter is greatly decreased, energy consumption can be reduced, and the metamaterial phase shifter is wide in phase shift range, low in cost and simple to manufacture.
