This paper examines the Goos-Hanchen effect for near-zero index metamaterials using fractional dual fields as the excitation source. The behavior of reflection coefficient, phase, and GH effect for ENZ/MNZ metamaterial is analyzed, considering both lossless and lossy materials. The impact of fractional parameter variation on these quantities is carefully observed.
The purpose of this paper is to examine the Goos-Hanchen-effect (GH-effect) for near-zero index metamaterials taking fractional dual fields as the source of excitation. Fractional dual fields are intermediate states between the s-polarized and p-polarized fields. The behavior of reflection coefficient, corresponding phase, and GH-effect, for epsilon-near-zero (ENZ)/munear-zero (MNZ) metamaterial is analyzed. Both lossless and lossy ENZ/MNZ metamaterial are treated in this regard. Impact of variation of fractional parameter on the behavior of reported quantities is noted in detail.
