SBIR Phase II: Development of a Compact, Lightweight Millimeter-Wave Source

这一小型企业创新研究第二阶段项目将涉及一种新型毫米波源(MWS)的实验研究，该毫米波源将为许多民用和军用应用提供短波辐射。MWS是基于铅笔电子束和旋转波场之间的新型同步相互作用。我们的第一阶段研究证实，与传统的毫米波源相比，MWS将在总体尺寸和重量方面提供数量级的改进，这将使这些新设备更简单、更实惠，并可用于各种应用。这些设备的一些应用包括高分辨率雷达、卫星通信系统、功率传输和聚变等离子体的电子回旋共振加热。此外，由于MWS不需要聚焦磁场，因此它应该适用于机载和移动应用，以及对尺寸、重量和效率至关重要的其他商业应用。在第二阶段对这一概念进行了详细的实验分析，以评估光束传输、最大输出功率、效率和增益等关键问题。一旦成功开发，MWS将成为新一代毫米波源的基础，能够在非常紧凑和轻便的封装中以高效率产生高功率超高频辐射。

This Small Business Innovation Research Phase II project will involve the experimental study of a novel millimeter-wave source (MWS) that will provide short-wavelength radiation for numerous civilian and military applications. The MWS is based on novel synchronous interactions between a pencil electron beam and rotating wave fields. Our Phase I studies confirm that the MWS will offer order of magnitude improvements in the overall size and weight when compared to conventional millimeter-wave sources which will make these new devices less complex, more affordable, and readily available for a diversity of applications. Some of the applications for these devices include high-resolution radar, satellite telecommunications systems, power beaming, and electron cyclotron resonance heating of fusion plasmas. Also, due to the fact that the MWS does not require a focusing magnetic field, it should be suitable for airborne and mobile applications, as well as other commercial applications where size, weight, and efficiency are critical. Detailed experimental analysis of this concept is proposed during Phase II in order to evaluate key issues such as beam transport, maximum output power, efficiency and gain. Once successfully developed, the MWS will be the basis for a new generation of millimeter-wave sources capable of producing high-power ultrahigh frequency radiation with high efficiency in a very compact and lightweight package.
