Abstract

The intention of this research is to study the relation dispersion of magnetic polariton generated in metallic antiferromagnet material with finite thickness numerically. The relation dispersion equation is solved in a various thickness, so that the affect of thickness in relation dispersion structure could be understood more clearly. The method used in solving relation dispersion is finding root by bisection. The results show that the structure of relation dispersion ghraphic for 0,2 cm thickness is the same with the relation dispersion graphic for semi infinite geometri. The bulk polariton became diskret below 0.2 cm thickness, and the quantization tend too decrease if the thickness of material is reduce. The bulk polariton disappear when the thickness of material is reduced to 2 ım. The number of surface polariton will have two branches in each direction of propagation when the material thickness is diminished to 20 ım. The distance between branches tend to larger if the thickness of materials became thinner.
