The invention belongs to the technical field of electromagnetic wave polarization detection, and particularly discloses an efficient microwave polarization detection device based on a photonic spin Hall effect. For the detection device, electromagnetic wave to be detected is decomposed into left-hand circularly polarized beam and right-hand circularly polarized beam through the efficient photonic spin Hall effect, the module values and phases of the left-hand circularly polarized beam and right-hand circularly polarized beam are respectively measured, and backstepping is carried out to obtain the polarization of the electromagnetic wave to be detected. The photonic spin Hall effect is realized through linear geometry Berry phase gradient of total-reflection type meta-surface with a spin structure.

The operating frequency of the device is 10-14GHz, and the structure constants of meta-atoms are scaled in equal proportion or redesigned, so that the operating frequency can be applied to other operating frequency ranges.

Provided are a method of generating strong spin waves, a method of simultaneously generating spin waves and electromagnetic waves, a logic operation device using spin waves, a variety of spin wave devices employing the same, and a method of controlling phases of spin waves. In the method of generating spin waves, strong spin waves are generated by supplying various shapes of energies to a magnetic material in which a magnetic vortex and magnetic antivortex spin structures exist separately or together. When energies are applied to a patterned magnetic material so that magnetic vortex or magnetic antivortex can be generated, a strong torque is generated in a vortex core so that strong spin waves can be generated from the vortex core. The spin waves generated in this way have large amplitudes, short wavelengths, and high frequencies. In the logic operation device using spin waves and the spin wave devices employing the same, wave factors of frequency, wavelength, amplitude, and phase of a spin wave generated by the method of generating spin waves are controlled and wave characteristics such as reflection, refraction, transmission, tunneling, superposition, interference, and diffraction are used. According to the present invention, logic operation spin wave devices capable of performing ultra-high speed information processing and various shapes of optical devices using waves in optics can be reconstructed using spin waves.
