Patent number: 11747518Abstract: The disclosure provides a self-biased magneto-optical non-reciprocal metasurface device. The device includes substrate layer and a sub-wavelength structure layer. The substrate layer is a material layer with a refractive index of 1 to 5 in a microwave frequency band. The sub-wavelength structure layer includes a plurality of square columnar elements arranged in a matrix period with equal period in row and column directions. The square columnar elements include magneto-optical material. The adjustment of phase and amplitude of a circularly polarized electromagnetic wave is achieved by changing the length, width and height of the square columnar elements, and thus the device attains a desired isolation and insertion loss at a center frequency f0. The parameters of the magneto-optical material are: coercivity Hc?1000 A/m; remanence Br?1 kGs; a voigt parameter of a permittivity tensor or permeability tensor in a working frequency band?0.01.Type: GrantFiled: March 15, 2021Date of Patent: September 5, 2023Assignee: UNIVERSITY OF ELECTRONIC SCIENCE AND TECHNOLOGY OF CHINAInventors: Lei Bi, Weihao Yang, Jun Qin, Jiawei Long, Longjiang Deng

Patent number: 10972425Abstract: Embodiments of this application disclose a method for parsing a service platform address by a server. The server receives a DNS parsing request sent by a terminal, the DNS parsing request including a to-be-parsed domain name. The server then obtains target IP information of the terminal based on the DNS parsing request. When the target IP information has a corresponding target user-defined line, the server obtains a preset first parsing record based on the target user-defined line. The server then sends to the terminal a first IP address corresponding to the to-be-parsed domain name based on the preset first parsing record. As such, a corresponding IP address range can be defined using a user-defined line, so that a terminal within the IP address range can obtain a specific IP address corresponding to an access domain name, and provide a service to a user within a more accurate range.Type: GrantFiled: March 22, 2019Date of Patent: April 6, 2021Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Jiangqi Wu, Fengbo Jiang, Hao Hu, Jun Qin
