Abstract
Five-layer slab a waveguide combined with a metamaterial has been studied. The central layers were the metamaterial and a normal material in the core of waveguide. The dispersion relation, field formulas, power formulas and the power flux formula has been derived. The waveguide property was controlled by changing the permittivity and permeability and thicknesses of the layers. The presence of metamaterial contributes to cut-off the mode TEo and other modes were propagated to backward. The stopping light was determined using the power flux value. However, the negative values of it refer to the backward direction of propagation. Furthermore the stopped light can be achieved in a certain value of power. Our results found it is good for different applications in communication and controlling.
