The Prevention of Multipactor Discharge in Rectangular Waveguide Loaded with Uniazial Metamaterial
Uniaxial metamaterial is used to reduce the possibility of multipactor discharge in rectangular waveguide. Single-negative permeability metamaterial can produce both double positive and double negative passband below the cutoff frequency of the hollow waveguide, de-pending on the orientation of its optic axis. The metamaterial is inserted in the middle of the waveguide, repeated along the direction of the axis. The TE wave is guided in the region of the uniaxial media. In the other region around, the wave becomes evanescent and attenuates exponentially. As a result, the normal component of electric fleld reduces sharply near the metal boundary, which in agreement with the simulation results. So the probability of electron emission at the metal surface would decrease.
