摘要: Metamaterial though is a new research area in electromagnetic engineering has attracted many investigators recently. The loading of these metamaterial elements have been presented here. My thesis carried out a parametric on rectangular waveguide with SRR metamaterial aim at investigating dimensional and electrical properties on the behavior of the backward wave mode on the dispersion diagrams. By inserting identical SRRs on two side walls of the rectangular waveguide create a pass-band below the waveguide cutoff frequency, thereby supporting backward travelling waves. SRRs are negative permeability media periodic structures loading into rectangular waveguide possess backward wave mode existing within the narrow pass-band below the cutoff frequency. Parameters involved in the design configuration have been investigated and their effects and influences on the appearance and locations of the backward wave mode on dispersion diagrams have been analyzed. A range of parameters that can be used to produce a better design and obtained good results as expected were identify. One major success of this study conducted is a way of computing the CST simulation in the shortest period of time which does not only speed up the work but ease the tension of the work. Optimization of the design parameters has been presented. This method shows the overlapping areas of the parameters involved. Another method called the polynomial curve fitting technique for modeling the estimated data from the dispersion diagrams have been presented too.
