Goos-Hanchen-effect for near-zero-index metamaterials excited by fractional dual fields

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.

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.
