We propose to investigate innovative, wideband, traveling-wave tubes (TWTs) compatible with three-dimensional (3D) micro-electro-mechanical systems (MEMS) fabrication techniques for millimeter or sub-millimeter wave applications. At least three novelinteraction circuits designed around MEMS fabrication technology will be investigated, as well as a novel electron beam source using field emission a ...

From consultations with the Army program manager, it was determined that the Army has a strong need for improved amplifiers in the W band. Accordingly, the proposed Phase II overall technical objective is to develop a 10 W, W-band prototype planar helix TWT. In Phase I, we addressed improving the repeatability, cost and yields of conventional Ka-band TWTs by introducing novel circuits, beam sou ...

CBL Technologies and Stanford University propose to develop and characterize a unique quantum dot microdisk source for high-power laser operation in the low terahertz frequency regime. The source will be used in military applications such as chemical and biological sensing, imaging and communications, as well as emerging commercial applications in medicine and biology. The source contains two co ...

In Phase I a revolutionary system for digital imaging microscopy was demonstrated. The system is based on the newly-developed imaging technology of Wavefront Coding (WFC). WFC employs specialized aspheric optics and digital processing to greatly increasethe depth of field or depth of focus. WFC simultaneously decreases the size, weight, and cost of a variety of digital imaging systems. Depth o ...

This work will explore the relevant parameter space and continue development of a sulfur-tolerant, direct JP-8 fuel cell using the liquid tin anode SOFC. This work will review potential liquid metal anodes for direct JP-8 applications followed by a characterization of the physical processes involved in power production. A mathematical model will be developed to predict the behavior of the cell, in ...

The CSA-UCDavis team proposes to develop a soil measurement device to allow for rapid and accurate measurement of soil parameters in order to rapidly and accurately characterize the terrain. The device will be man-portable but also allow for mounting to a small robotic vehicle. Parameters that will be measured include but are not limited to cone index, soil friction index, as well as soil shear ...

One deficiency of existing planning systems is that they may report mission-level progresses, but are incapable of associating them with desired mission-level outcomes/impacts. USG agency planners and other organizations have produced general frameworks for measuring outcomes/impacts such as MPICE, but clearly planning activities and outcome/impact measure activities remain disconnected. We aim to ...

The Phase I program objectives were successfully completed. In addition, novel ideas were developed that will be of use in the Phase II program and in the field of algorithm development and sensor characterization in the laboratory. Work on new algorithmswas initiated to optimize wavelength selection for vapor and aerosol detection, a detailed design for obtaining sensor detection statistics in th ...

CO2 laser based sensors are poised to enter the next phase of development defined by smaller, lighter systems based on heterodyne detection. This will have significant impact on the Artemis acquisition program, other military deployments, and for homeland defense systems. The program Phase I objectives are to perform supporting analysis and develop designs for the critical heterodyne system compon ...
