ABSTRACT
Artificially designed transformation medium offers great opportunity to control the field distributions inside a waveguide. By rigorously solving Maxwell’s equations in cylindrical and rectangular waveguides, we show that filling waveguides with properly designed transformation medium with a space gradient can reduce the electric field at boundary to zero. Full-wave finite element modeling is also performed to confirm this point. This property can be used to reduce the probability of multipactor discharge at the surface of conductor inside a waveguide.
