Abstract: Various embodiments provide a method for determining polarization information and a device thereof. In those embodiments, a first polarization information set sent by a transmitting device can be received by the receiving device. The first polarization information set includes at least one piece of first polarization information. A quality set comprising at least one quality of a received signal can be determined by the receiving device. The first polarization information corresponds to a quality of the received signal in the quality set, and the received signal is sent by the transmitting device to the receiving device through a non-line-of-sight channel. An optimal quality in the quality set can be determined by the receiving device. The optimal quality has a minimum degradation degree of the received signal in the quality set. The receiving device can then send the first polarization information corresponding to the optimal quality to the transmitting device.

Abstract: Embodiments provide a frequency selective surface (FSS). The FSS includes uniformly arranged FSS units. Each FSS unit includes a dielectric slab, a cross-shaped metal patch, and N square-ring metal patches. The cross-shaped metal patch is adhered to a first surface of the dielectric slab, and divides the first surface of the dielectric slab into four parts. Each part has a same size and a same quantity of the square-ring metal patches. The N square-ring metal patches are adhered to the first surface of the dielectric slab, and are arranged uniformly, and N is a positive integer power of 4. Lengths of the cross-shaped metal patch in two mutually perpendicular directions are equal, and both a length in each direction and a width of a gap between adjacent patches need to meet a specific condition.
