Frequency selective surfaces for high-power microwave (HPM) applications

Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012
Despite the significant number of studies conducted on periodic structures and frequency selective surfaces, few studies have examined the power handling capability of these structures in any detail. In this paper, we examine the transient power handling capability of a class of frequency selective surfaces composed entirely of non-resonant ...

Design of Novel VLASOV-type Antennas for High Power Microwaves (HPM)

2007 IEEE 34th International Conference on Plasma Science (ICOPS), 2007
Summary form only given. In this paper, Vlasov antenna is studied systematically by the moment method (MM) and finite difference time domain (FDTD). Based on the simulation results, the process of mode conversion in the waveguide and radiation through the aperture is described. The measurement results agree well with the simulation. Based on our study,

Innovations and Fundamental Insights of Advanced Field Emission Cathodes for High Power Microwave (HPM) Sources

2007 IEEE Pulsed Power Plasma Science Conference, 2007
One of the key remaining challenges for HPM (> 100 MW, 100 A/cm2 and negligible evidence of cathode plasma. Experimental I-V characteristics of monolithic-metal cathodes suggest anomalously high local surface electric field enhancements (> 100) combined with small fractions ( 0.01) of the cathode surface responsible for the emission. These collective

Broad Band 2×4 Horn Antenna Array for High Power Microwave (HPM) Systems Application

Journal of Advanced Research in Applied Sciences and Engineering Technology
In this paper, a 2 × 4 planar horn antenna array for high power microwave (HPM) system applications is introduced. The pyramidal, E-plane-plane, H-plane and the two plates of horn antenna element are analyzed using HFSS. The pyramidal horn is arrayed in a 2 × 4 configuration structure to obtain a high gain for HPM applications.
