Long pulse operation of a high power microwave source with a metamaterial loaded waveguide

We present the design and the experimental results of a metamaterial (MTM) based backward wave oscillator (BWO). The electron beam propagates through a waveguide loaded with two MTM plates, with the design of one plate being the reverse of the second plate. The design mode is a fundamental hybrid deflecting mode at 2.4 GHz with a negative group velocity… CONTINUE READING
