According to one embodiment, a subscriber station configured to communicate with one or more base stations in a wireless communication network. The multi-thread packet processor transfers a data packet from a flexible data input buffer to a packet task manager, dispatches the data packet from the packet task manager to a multi-threaded pipelined analysis machine, classifies the data packet in the analysis machine, modifies and forwards the data packet in a packet manipulator. In an embodiment, a portion of the non-planar surface has at least one layer of nanostructures disposed thereon. Curving surfaces are formed in side face parts on both sides of the comb main body, and through-holes communicating with the holes are formed in concave parts of the curving surface.
