Abstract
72258S03-I Generation of high power electromagnetic waves requires specialized high power electronics. Specifically, high energy density capacitors are necessary to support high-energy microwave systems. Current capacitors are inefficient, resulting in a bulky and inductive power source. Practical, efficient power supply systems require materials with energy densities at least twice that of existing materials. To date, composites have shown little promise due to the detrimental effects of the ceramic filler on voltage capabilities and the fact that the ceramic has only a second order effect on dielectric constant. This project will develop an advanced dielectric material system based on structured, nano-composites. The technology promises more compact (greater than 4x size reduction), lower inductance power supplies for a range of high power system applications. Phase I will use a nanopowder filler to create more uniform composites with fewer defects that cause breakdown. Unique structures will be created through dielectrophoritically aligning particles, thereby increasing the effect of the ceramic filler on dielectric constant. Commercial Applications and Other Benefits as described by awardee: The development of high energy storage systems with reduced size and weight are important for a wide range of uses. Military pulsed power applications include electromagnetic armor and guns, microwave and laser sources, and antipersonnel mine detection. Commercial applications include portable defibrillators, explosive material detection, and portable defect detection in airplane bodies.
