To increase the output power of the surface wave oscillator (SWO) at the terahertz band, this paper presents a new type of coaxial-structured SWO, and its dispersive curve of TM01 mode is calculated numerically. The working properties of this new device are numerically simulated by using the self-developed fully electromagnetic particle code UNIPIC. Numerical results show that the working frequency of the coaxial-structured SWO is identical to that of the cylindrical-structured SWO, and the output power from this new coaxial-structured SWO is 67.8% more than that from the cylindrical-structured SWO, and the output mode of the terahertz wave is the transverse electromagnetic mode.
