Image of FIG. 1.
FIG. 1.

(a) Diagram of the deflection of terahertz rays passing through an artificial material that is induced by a refractive index gradient. Panel (b) depicts the experimental configuration where the terahertz detector can be positioned to any angle, , around the sample, and a magnetic field is applied parallel to the terahertz electric field polarization. The orientation of the regions comprising the sample is indicated by the numbers ranging from 1 to 5, where the corresponding are 0.67, 0.73, 0.81, 0.92, and 1, respectively.

FIG. 2.

(a) Time domain terahertz signals transmitted through the artificial material and measured at various . Panel (b) depicts the on-axis terahertz signal transmitted through the empty sample cell. Panel (c) depicts the time averaged energy flux of terahertz signals measured at various for the artificial material (triangles), sample A (circles), sample B (diamonds), and empty cell (squares). The values of for the empty cell have been scaled down by approximately an order of magnitude and a Gaussian regression line is applied to the data using a least-squares estimation. The inset of (c) depicts the on-axis terahertz signals transmitted through sample A (upper) and sample B (lower).

Image of FIG. 3.
FIG. 3.

(a) The time averaged energy flux of terahertz signals transmitted through the artificial material and measured at various for external -field strengths of 0 mT (squares), 27 mT (diamonds), 45 mT (triangles), 55 mT (x), 69 mT (circles), and 78 mT . A Gaussian regression line is applied to the data using a least-squares estimation and the direction of the arrow signifies the movement of the curve as is increased. Panel (b) depicts the deflection angle of the terahertz signals for the aforementioned -field strengths.
