Joint services electronics program

The research is organized under two theme areas: High speed wide band elements for high frequency electronics and new architectures for parallel computation. The former has 5 work units and one supplement ranging from optoelectronic, Gunn-effect, ultra-short-channel Si and superconductive devices to new techniques for electromagnetic scattering computation. The second theme area has 3 work units which cover research projects ranging from CAD techniques for the synthesis of very large circuits and investigations of alternative architectures for parallel computation to devices for use in neural networks. One project is concerned with biologically-based neural networks. Included are four descriptions of especially significant accomplishments: (1) the discovery of hot electron effects in devices which occur at voltages less than the bandgap potential, (2) new designs for Gunn-effect oscillators which have unprecedented power and efficiency, (3) achievement of three unique guided wave devices, and (4) a technique to achieve fault tolerance in artificial neural networks.
