Omnidirectional transmission switching in epsilon-near-zero metamaterials

Contrary to popular belief, conventional wisdom states that light bends away from the normal when it passes from high to low refractive index media, here we demonstrate that the transmitted power almost parallels to the normal for all angles of incidence when light passes from arbitrary high refractive index medium to epsilon-near-zero metamaterial. This counterintuitive to the conventional Snell’s law behavior is induced by material loss that switches the transmission angle from grazing to normal direction in epsilon-near-zero metamaterials. This property has potential applications in communications to increase acceptance angle and energy delivery without using optical lens and mechanical gimbals.
