2.6 Reflection and Refraction by Zero-Index Metamaterials

(a) θ 1 = 30 deg
(b) θ 1 = 45 deg
(c) θ 1 = 60 deg
Fig. 2.20 Almost normal emergence irrespective of angle of incidence. Left-hand side: incident
wave propagating toward the ZIM–air boundary for a θ 1 = 30 deg, b θ 1 = 45 deg, and c θ 1 =
60 deg. Right-hand side: Refracted beam emerging from the ZIM–air boundary. In all the three
cases, θ 2 ≈ 0.
