Award Data

Solid-state electronic devices are often subjected to high voltage transients generated by switching, lightning, or electrostatic discharge. These transients can cause mission critical components to fail. Varistors are increasingly used to avoid such failures. The current varistor devices, however, are not well suited for high frequency applications and the increasing trend towards device miniatur ...

Inductors are essential components of military and commercial power management and electronic systems. Existing ferrite based inductors have reached a technology plateau that allow only marginal improvements in performance per unit volume. It is anticipated that the future inductor based technologies, such as EMI suppression, would require significantly higher energy density inductors. Fundamental ...

We propose the experimental investigation of a frequency-doubling millimeter-wave amplifier (MWA) that has diverse applications such as short-wavelength radiation sources for sensors and associated systems. The MWA is proposed as a very compact, light-weight RF source in which an electron beam is injected into a deflection cavity operating at the drive frequency. A transverse magnetic field produc ...

A novel technological approach was recently devised by Sumi Tech engineers to fabricate multilayer electronic components, which enables the manufacture of devices with very high volumetric efficiency and reliability. Inexpensive electrode materials such as copper, or aluminum are potential candidates, since the process takes place at relatively low ambient temperature (e.g., less than 400 C), thus ...

The advanced technology described in this proposal promises to increase the performance of laboratory and, specifically, tabletop x-ray lasers by up to an order of magnitude. Such gains in performance coupled with compact technology will lead to the introduction of the world s first table-top, commercial x-ray laser. Tetra proposes to develop an advanced driver for the laboratory laser based upo ...

Demand for micrometer size metal powders is increasing rapidly as new technologies emerge which can make use of their unique characteristics. One rapidly growing application requiring such powders is metal injection molding, a powder metallurgy process for forming near-net-shape components with higher dimensional accuracy than earlier processes. A significant need also exists for micrometer size s ...

Liquid rocket engine performance can be dramatically improved by increasing the wall temperatures for operation concurrent with a reduction in the component weight. The bipropellant fuel combustion temperatures are between 3000 "approx" 3500 C. The conventional thrusters and exit nozzles made of niobium alloys have a maximum operating temperature limit of 1600 C. A regenerative cooling technolo ...
