2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting.
We present results of simulation, fabrication, and testing of an S-band narrow-wall longitudinal slot antenna designed for high-power-microwave (HPM) systems. A key aspect of the proposed antenna structure is the use of longitudinal slots in the narr

An apparatus for generating quasi-free-space microwave-driven plasmas has been designed, constructed, and tested. The plasma is driven by a multi-kW, ∼5 GHz microwave beam focused at the center of a vacuum chamber using a Koch-type metal plate lens

The publication of this 17th Special Issue on High Power Microwave (HPM) Generation continues a series first published in December 1985. Since the first volume, the entire HPM field has undergone tremendous changes and advances. While initially being

We present system considerations for the design of a tunable mesoband source based on a parallel-plate Blumlein architecture. Here, we discuss the switching characteristics, electrode shaping, and tunability of a system designed to operate from 100 M

Quarter-wave switched oscillators (SWOs) are an important technology for the generation of high-power mesoband waveforms. The operation of these SWOs has been discussed for the past several years, but a detailed discussion of the design of these sour

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI).
Metal plate lens antennas were designed and constructed for a high power microwave zoom antenna concept comprising a horn feed antenna and two metal plate lenses. Good agreement was found between experiment and simulation. This antenna provides true
