介绍了用于低太赫兹回旋行波放大器的两种基模矩形-圆波导输入耦合器的设计。优化了带Bragg反射器的t结输入耦合器和多孔定向耦合器，工作在360 ~ 384 GHz（所提出的陀螺- twa带宽）之间。t结耦合器和多孔耦合器分别实现了10%和35%的带宽。讨论了低太赫兹波耦合器拓扑结构的优点和潜在局限性，以及具有挑战性的亚毫米波元件制造方法。
The design of two fundamental mode rectangular-to-circular waveguide input couplers for a low-terahertz gyrotron-traveling wave amplifier (gyro-TWA) is presented. A T-junction input coupler with a Bragg reflector and a multiple-hole directional coupler were optimized for operation between 360 and 384 GHz, the proposed gyro-TWA bandwidth. The T-junction coupler and the multiple-hole coupler achieved the respective bandwidths of 10% and 35%. The benefits and potential limitations of the low-terahertz wave coupler topologies are discussed alongside the challenging manufacturing methods of the submillimeter-wave components.
