摘要

摘要: 探索和发展更高频率和更高功率水平的电磁波源是电子器件长期以来的重要发展方向.本文介绍了基于电子回旋脉塞原理发展起来的电子回旋器件,该类器件在毫米波-太赫兹波段具有高功率的优势.系统探讨了电子回旋器件所面临的欧姆损耗、模式竞争以及对强磁场的依赖性等几个基础问题,指出在深入研究模式竞争机理的基础上发展高阶模式和高次谐波系统将有助于推动电子回旋器件实现高功率、高效率和高稳定性,这对促进器件向太赫兹频段发展具有参考意义.

Abstract: It is always an important tendency of the electronic power devices to explore and develop electromagnetic radiation sources operating on higher frequency and with higher power capability. The cyclotron electron device which was developed based on the mechanism of the electron cyclotron maser and with the excellent advantage of radiating high power in millimeter-to-terahertz range was introduced. It systematically discussed about the fundamental challenges encountered by the electron cyclotron devices, including the strong ohmic dissipation problem, the mode competition problem, and the unavoidable dependency on operating with strong magnetic field. Finally, it was proposed that, on the basis of fully exploring the physical mechanism of the mode competition, to develop higher order mode circuit and higher harmonic interaction system would be very helpful to realize the high power, high efficiency and high stability cyclotron electron devices, which is of important reference for guiding devices development towards terahertz band.
