DARPA: Innovative Vacuum Electronics Science and Technology

DARPA: Innovative Vacuum Electronics Science and Technology has the below focus areas but not limited to:

•          Advanced modeling: High-fidelity, geometry-based, multi-physics, numerically efficient, end-to- end modeling and simulation techniques for analysis, synthesis, and optimization that lead to first- pass design success.
•          Advanced manufacturing: Advanced manufacturing techniques for beam-wave interaction circuits and other mm-wave tube components.
•          Innovative beam-wave interaction structures: Innovative beam-wave interaction structures with wide band width and high peak and average power handling capacity that are designed for manufacturability at mm-wave frequencies above 75GHz.
•          Cathode science and technology: Experimental science leading to a more complete fundamental understanding of electron emission enabling the a priori design of low-temperature (<800°C), high current density(>20A/cm2), long-life (>10,000 hours) cathodes.
