亚毫米波频谱（100GHz-1THz）为开发极快的短距离通信以及用于安全和生物医学传感应用的高分辨率传感器/成像仪设备提供了前所未有的机会。亚毫米波提供了巨大的带宽和频谱，使数据速率超过100Gbit/s的短距离通信成为可能。用于安全和隐蔽武器探测的高分辨率成像是次太赫兹波的另一个主要应用。亚毫米波也是一种非常敏感的水探针，对生物分子的行为有重要影响。目前的太赫兹系统，包括源/放大器和探测器，缺乏新兴应用所需的波束形成、紧凑的尺寸和低功耗等特性，而且体积庞大，价格昂贵。为了研究和开发具有所需特性的负担得起的技术，建议研究的主要步骤是：1。探索最佳亚毫米波特性在近距离通信和传感中的新兴应用2。基于纳米半导体工艺的最新进展，开发新一代低成本但敏感的太赫兹源，探测器和多波束收发器。3. 将源/检测器和收发器集成到低成本封装中。4. 对正在研究的设备进行全面的测试、表征和校准。为了实现所提出的研究目标，需要研究和克服电路，系统，架构，天线，收发器和天线集成方面的许多研究挑战。新成像仪的核心是一个多通道多波束形成集成电路，需要非常高效和非常低的功耗。

Sub-Millimeter wave spectrum(100GHz-1THz) offer unprecedented opportunities to develop extremely fast short-range communication as well as high resolution sensor/imager devices for security, and biomedical sensing applications. Sub-mm-wave offers a massive bandwidth and spectrum where short range communication with data rate of over 100Gbit/s can become possible. High resolution imaging for security and concealed weapon detection is another major application of sub-terahertz wave. Sub mm-wave wave is also very sensitive probe of water, which has a significant influence on the behavior of biomolecules. Current THz systems including sources/amplifiers and detectors lack the characteristics such as beamforming, compact size and low power consumption needed for the emerging applications and are quite bulky and expensive. To investigate and develop affordable technologies with required characteristics the main steps of the proposed research are: 1. Exploring the best Sub-mm-wave characteristics for the emerging applications in short-range communication and sensing 2. Developing a new generation of low-cost but sensitive THz sources, detectors, and multi-beam transceivers based on recent advances in nano-metric semi-conductor processes. 3. Integration aspects of sources/detectors and transceivers into low-cost package. 4. Comprehensive test, characterization, and calibration of the devices under investigation. To achieve the objectives of the proposed research, many research challenges in circuits, systems, architectures, antennas, integration of transceivers and antennas need to be investigated and overcome. The heart of the new imager is a multi-channel multi-beam beam-former integrated circuit that needs to operate very efficient and very low power.
