Embodiment Construction
[0034] The embodiment of the present invention provides a tunable metamaterial polarizer and its manufacturing method, which solves the technical problems of large volume, difficulty in integration, and very limited working wavelength range in the prior art, and realizes reduced volume, easy integration, and broadened working range. The technical effect of the applicable range of wavelengths.
[0035] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:
[0036] A metamaterial array composed of a doped semiconductor metamaterial resonant unit on the substrate, the first power port of the resonant unit is connected to the positive pole of the regulating power supply, and the second power port of the resonant unit is connected to the negative pole of the regulating power supply, avoiding the linear polarization The polarizer is constructed by using a polarizer and a quarter-wave plate, whi...
