摘要: 为了提高太赫兹表面波振荡器的输出功率,本文提出了同轴结构的表面波振荡器模型,并且获得了该同轴结构TM01模的色散曲线,采用自行研制的全电磁粒子模拟软件UNIPIC对提出的同轴结构表面波振荡器进行了模拟,结果表明器件的工作频率与圆柱结构时的表面波振荡器相同,在输出端以TEM模式传输太赫兹波,输出功率相比圆柱结构的表面波振荡器输出功率水平提高了67.8%.Abstract: 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.
