This proposal will develop the world's highest power (kW), broadest instantaneous bandwidth, frequency agile amplifiers operating in the mm-wave/terahertz range. The gyro-amplifiers offers a unique opportunity to fill a long standing gap in the generation of high power coherent millimetre and sub millimetre wave radiation with its promise of amplification with an unprecedented 20% instantaneous bandwidth and an unrivalled power of 5kW at 94 GHz. Building on the recent success of "W He et al PRL 2013, 110, art 165101, 2013", the mm/sub-mm wave gyro-TWA will enable a paradigm shift in what is achievable for a ground based, cellular telecommunications network by providing tera-bit data rates. This is possible due to the fact that the wireless gyro-TWA operating at sub-THz frequencies does not need to use opto-electronic components currently limiting data rates of optical schemes. Another major area of development is the possibility of exploiting the world leading gyro-TWA to be used in Electron Paramagnetic Resonance (EPR) and Dynamic Nuclear Polarisation (DNP) spectroscopy which is currently hampered by the lack of high power sources and especially broadband amplifiers of terahertz radiation. In addition the gyro-TWA would be an ideal source for cloud profiling radar and the detection of atmospheric pollutants because the atmospheric absorption, penetration and scattering losses, practical stand-off systems require considerable power, typically hundreds of watts. Other applications include high frequency long range security imaging, space situational awareness (detecting space debris), terrain mapping (volcano monitoring), radar and long range, high bandwidth, line of sight communications and real time video-rate detection of hidden explosives and illegal drugs.

该提案将开发世界上功率最高（kW）、瞬时带宽最宽、工作在毫米波/太赫兹范围内的频率灵活放大器。陀螺放大器提供了一个独特的机会，填补了在产生高功率相干毫米波和亚毫米波辐射方面长期存在的空白，其承诺的放大具有前所未有的20%瞬时带宽和94 GHz时5kW的无与伦比的功率。基于“W He et al PRL 2013, 110, art 165101, 2013”最近的成功，毫米/亚毫米波陀螺仪- twa将通过提供太比特数据速率实现地基蜂窝电信网络可实现的范式转变。这是可能的，因为在亚太赫兹频率下工作的无线陀螺twa不需要使用目前限制光学方案数据速率的光电元件。另一个主要的发展领域是利用世界领先的陀螺- twa用于电子顺磁共振（EPR）和动态核极化（DNP）光谱的可能性，目前由于缺乏高功率源，特别是太赫兹辐射的宽带放大器而受到阻碍。此外，陀螺- twa将是云剖面雷达和大气污染物探测的理想来源，因为大气吸收、穿透和散射损失，实际的隔离系统需要相当大的功率，通常为数百瓦。其他应用包括高频远程安全成像、空间态势感知（探测空间碎片）、地形测绘（火山监测）、雷达和远程、高带宽、视线通信以及隐藏爆炸物和非法毒品的实时视频速率探测。
