[HTML][HTML] High power long pulse microwave generation from a metamaterial structure with reverse symmetry
X Lu, JC Stephens, I Mastovsky, MA Shapiro… - Physics of …, 2018 - pubs.aip.org
Experimental operation of a high power microwave source with a metamaterial (MTM)
structure is reported at power levels to 2.9 MW at 2.4 GHz in full 1 μs pulses. The MTM
structure is formed by a waveguide that is below cutoff for TM modes. The waveguide is
loaded by two axial copper plates machined with complementary split ring resonators,
allowing two backward wave modes to propagate in the S-Band. A pulsed electron beam of
up to 490 kV, 84 A travels down the center of the waveguide, midway between the plates …
