The display of digital holograms is hampered by the fact that the resolution of existing display media is usually lower than the wavelength of light. To solve the problem, the generation of full parallel digital Fresnel holograms is developed to make possible their display on specially designed low .....

In general, a linearly polarized wave can be changed into an elliptically or circularly polarized wave by using a wave polarizer. However, adding an external polarizer will increase the size and complexity of the antenna. In this patent, a polarizer is directly integrated with the omnidirectional LP.....
