In this paper, the design of structures was done by using of classical discrete layers method. Classical structure was made by periods of two layers with high and low refractive index. In order to decreasing notch width of filter, one material with two different packing density was used in structure instead of two different materials. Finally, sidelobes of transmittance band were decreased by optimization of outer most layers and inserting a match layer. This layer is placed on the first layer after incident medium.
