Abstract :
In this paper a multilayer electromagnetic band gap (EBG) structure is proposed as a size-reduced solution for application in Magnetic Resonance systems operating at around 300MHz. The reflection phase coefficient at normal and oblique incidence is studied, and the dispersion diagram is used to determine the TE and TM surface wave suppression band gap. The proposed EBG structure is designed to exhibit very small deviation in the resonant frequency versus angle of incidence and to exhibit a stop band gap related to the quadrature reflection phase criterion.
