Abstract
To create an active phase-gradient metasurface relying on variable inductance, an impedance converter is used to realise positive inductance values. By varying the inversion coefficient, a variation of the inductance can be achieved electronically. A prototype of the circuit is fabricated and tested. Different inductance values are obtained with respect to the inversion coefficient used. Such circuit can be readily applied to an LC resonant cell to control the phase responses. A potential application for beam steering is further numerically verified.
