Abstract

Microfabricated folded waveguide traveling wave tubes (FWG-TWT) are potential compact sources of wideband (/spl sim/20% instantaneous bandwidth), high power (0.01 - 1 W) THz radiation. We present numerical simulations indicating that a 560 GHz, 56 mW, 1% (intrinsic) efficiency oscillator is realistically achievable, and a 400 GHz amplifier with gains between 10 and 30 dB are feasible with circuit lengths of a few centimeters. We also discuss a scale-model experiment at 50 GHz to investigate an oscillator concept using a recirculated power feedback approach.

使用微制造折叠波导行波管的紧凑太赫兹辐射源的综合模拟

微加工折叠波导行波管(FWG-TWT)是宽带(/spl sim/20%瞬时带宽)、高功率(0.01 - 1 W)太赫兹辐射的潜在紧凑源。我们提出的数值模拟表明，一个560 GHz, 56 mW, 1%(固有)效率的振荡器是可以实现的，一个增益在10到30 dB之间的400 GHz放大器是可行的，电路长度为几厘米。我们还讨论了一个50 GHz的比例模型实验，以研究使用循环功率反馈方法的振荡器概念。
