In this paper, it is shown that employing epsilon near zero metamaterials (ENZ) in the slow wave structure of a spatial harmonic magnetron can increase the efficiency and average output power of this type of magnetron. An approximate beam-wave interaction analysis which paves the way for introducing the ENZ loaded SWS is presented. Numerical simulations of the beam-wave interaction confirm the superiority of the ENZ loaded SWS to its conventional counterpart.
