Schematics of refraction and transverse shift.

(a) Schematics of the beam refraction from air to ① a positive-refraction-low-index medium, ② a negative-refraction-low-index medium, ③ a negative-refraction-high-index medium and ④ a positive-refraction-high-index medium are shown. (b) Theoretical calculation (solid curve) and experimental measurement (solid circle) of refraction angle (red) θt and relative transverse shift (blue) are plotted as a function of incidence angle θi.
