Abstract: The system obtains multiple unique identifiers associated with multiple UEs, where a unique identifier among the multiple unique identifiers identifies a UE among the multiple UEs. Based on the unique identifier, the system determines multiple technical capabilities associated with the multiple UEs. The system receives a request for one or more UEs, where the request includes a number of the one or more UEs and a desired technical capability associated with the one or more UEs, and where the request is specified at a level of abstraction that allows more than one UE among the multiple UEs to satisfy the request. Based on the request for the one or more UEs and the multiple technical capabilities associated with the multiple UEs, the system determines a subset of the multiple UEs satisfying the request, and sends a response to the request indicating the subset of the multiple UEs satisfying the request.

Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.
