Abstract: A terahertz carrier-envelope phase shifter includes a substrate, a first phase modulator and a second phase modulator, which are arranged on a surface of the substrate. The first phase modulator has a first phase modulation angle. The second phase modulator has a second phase modulation angle that is different from the first phase modulation angle.

A geometric parameter and the spatial position of a microstructure in the first or the second phase modulator are changed and the carrier-envelope phases of the terahertz pulse covers 0-2 ?.

Abstract: The present disclosure relates to the field of communication technologies and in particular to a user-distinguished finite-field resource construction method and a finite-field multiple access system. In order to solve the problem of the limitation of the multiple access resource in the current communication field, the present disclosure employs a user-distinguished finite-field resource construction method to construct a basic-field resource and/or extension-field resource, i.e. finite-field resource. During the use of the finite-field resource, each user sending a binary sequence is assigned one codebook marking symbols that 0 and 1 are respectively mapped into a finite field. The transmitter sends a corresponding finite-field symbol sequence. At the receiver, based on the received finite-field symbols, a finite-field symbol sent by each user can be determined uniquely and thus, a binary symbol sent by each user can be decoded. The present disclosure is applied to the finite-field multiple access system.
