Suitably designed metasurfaces can introduce phase discontinuity to the transmitted or reflected electromagnetic waves. Consequently, the transmitting wave can bend anomalously in a desired angle. Here, we demonstrate a metasurface in terahertz regime with super unit cell consisting of multiple micro-resonators exhibiting anomalous refraction. Careful modification of the inter-resonator distances inside the unit cell can lead to variable bending angle for the anomalously refracted wave.
