Abstract

A low-loss and high-effective-output-power terahertz (THz) folded waveguide (FWG) high-frequency circuit is proposed, fabricated, and tested. The circuit consists of several slow wave sections connected by a single period transition structure, in which the odd number sections are with the same slow wave unit cells and the even ones are with another same slow wave unit cells. To increase fabrication accuracy and reduce the circuit losses, both slow wave unit cells are designed to operate with phase shifts greater than 600°. The circuit, fabricated from oxygen-free copper (OFC) by using nano computer numerical control (nano-CNC) milling technology, exhibits excellent transmission characteristics in the cold test experiment, achieving a transmission loss of less than 1 dB/mm, corresponding a recorded equivalent conductivity of

$3.7\times 10^{{7}}$

S/m above 0.6 THz. The simulations with modified structural dimensions based on the fabricated sample indicate that the machining errors are below

$2\mu $

m, resulting in the frequency shift within 12 GHz. In addition, the low loss enables the saturated input power to be as low as 0.5 mW, while the maximum output power reaches 2.86 W with a 3-dB bandwidth of approximately 8 GHz.

新型低损耗 0.65-THz 多剖面折叠波导高频电路

本文提出了一种低损耗、高有效输出功率的太赫兹（THz）折叠波导（FWG）高频电路，并对其进行了制作和测试。该电路由多个慢波部分组成，通过单周期过渡结构连接，其中奇数部分使用相同的慢波单元，偶数部分使用另一个相同的慢波单元。为了提高制造精度和减少电路损耗，两个慢波单元都设计成相移大于 600°。该电路由无氧铜（OFC）通过纳米计算机数控（nano-CNC）铣削技术制成，在冷测试实验中表现出优异的传输特性，传输损耗小于 1 dB/mm，在 0.6 THz 以上记录的等效电导率为 3.7/times 10^{{7}}$ S/m。根据制作的样品修改结构尺寸后进行的模拟表明，加工误差低于 2 美元/毫米，因此频率偏移在 12 千兆赫以内。此外，低损耗使饱和输入功率低至 0.5 mW，而最大输出功率达到 2.86 W，3-dB 带宽约为 8 GHz。
