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.

亚毫米波频谱(100 GHz-1 THz)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/成像器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，可以实现数据速率超过100Gbit/S的短距离通信。用于安全和隐蔽武器探测的高分辨率成像是亚太赫兹波的另一个主要应用。亚毫米波也是对水非常敏感的探头，它对生物分子的行为有重大影响。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诸如波束形成、紧凑尺寸和低功耗等特征，并且相当庞大和昂贵。为了研究和开发具有所需特性的负担得起的技术，提出的研究的主要步骤是：1.为短距离通信和传感中的新兴应用探索最佳的亚毫米波特性2.基于纳米半导体工艺的最新进展，开发新一代低成本但灵敏的THz源、探测器和多波束收发机。3.将信源/探测器和收发信机集成到低成本封装中。4.对正在调查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，需要研究和克服在电路、系统、体系结构、天线、收发信机和天线的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器集成电路，它需要非常高效和非常低的功率。
