N2 - An innovative idea of shuffled structure of two quarter wavelength plates is proposed in this paper, which is supported by the numerical simulation results obtained through the application of the method of characteristics (MOC). In contrast to traditional anti-reflective coatings techniques, the proposed structure is a shuffled arrangement of two quarter wavelength slabs which are in theory evenly divided into N + 1 and N pieces and then stacked up alternatively. These slabs are made of non-magnetic (µr = 1) dielectric (εr > 1) materials respectively characterized by dielectric constants εr1 and εr2 having the relation of εr2 = (εr1)2 to allow maximum transmission. These 2N + 1 pieces are assembled such that there is always an εr2 piece between two εr1 pieces. Therefore, the proposed structure has the advantages of simple components and easy assembly. In the present simulation, the integer number N ranges from one to ten. The computational results are demonstrated in both time and frequency domains exhibiting that the proposed structure functions as a frequency selector.
