Magneto-inductive waveguiding using a step-defect line in a reconfigurable digital metasurface for wireless power transmission

In this paper, we present a reconfigurable digital two-dimensional metasurface consisting of an 8 × 8 matrix of specialized unit cells that can dynamically switch between two resonance modes at 11 MHz and 13.56 MHz. By carefully designing defect-based metamaterial cavities, flexible waveguides are formed while effe...
