On Fresnel-Airy Equations, Fabry-Perot Resonances and Surface Electromagnetic Waves in Arbitrary Bianisotropic Metamaterials

Abstract

We introduce a theory of optical responses of bianisotropic layers with arbitrary effective medium parameters, which results in generalized Fresnel-Airy equations for reflection and transmission coefficients at all incidence directions and polarizations. The poles of these equations provide explicit expressions for the dispersion of Fabry-Perot resonances and surface electromatic waves in bianisotropic layers and interfaces. The existence conditions of these resonances are topologically related to the zeros of the high-k characteristic function h(k) = 0 of bulk bianisotropic materials and taxonomy of bianisotropic media according to the hyperbolic topological classes [32,33].

Metasurface Holography with Multiplexing and Reconfigurability

“…As shown in Figure 6 b, it can excite symmetric and antisymmetric resonance modes at different incidence angles, and the tremendous difference between the two modes exhibits the potential for independent phase modulation. The proposed angle-multiplexed metasurface hologram can encode different holographical images under and incidence angles with TE polarization, as shown in Figure 5 c. Similar to this principle, Shuai et al [ 44 ] further proposed a Fabry–Perot (FP) [ 73 ] resonator meta-atom. The discrepancy between the critical resonance lengths of the surface plasmon and MIM nanocavity for different illumination angles allows modulating the phase and amplitude at the same time.…”
