Abstract: With the deepening of research, terahertz (THz) science and technology becomes increasingly prominent in many fields for both basic research and engineering applications. Radiation source, transmission and control, detection and sensing are three important
aspects that need to be explored in the further development of THz technology. The common basis of THz wave applications is to
make the effective interaction with the material for carrying information or transmitting power. To implement these processes, we
need to control the electromagnetic parameters like amplitude, phase, frequency, polarization, wavefront and the photonic parameters like spin and orbital angular momentum of THz wave. The above manipulation can be carried out directly at the radiation source or additional functional devices in the transmission process. In this paper, several representative source- and device-based THz manipulation technologies are introduced, and the basic principles, development history and latest progress are summarized. The development of THz manipulation technology will lay a solid foundation for the further application of THz wave.
