Abstract: A design of an active microresonator intended for the implementation of a reconfigurable metasurface applicable to B5G/6G wireless communication systems is proposed. The developed structure enables phase control of the transmitted electromagnetic wave and allows dynamic modification of the transmitted wavefront. The numerical simulations carried out in the Ka-band of microwave waves have confirmed the capability of wide-range phase tuning through the variation of varicap capacitance. The obtained results demonstrate the potential of employing the proposed metasurface in a new generation of wireless communications B5G/6G antennas for adaptive beam steering.

Keywords: Huygens principle, active metasurface, varicap, B5G applications, transmitted wave phase.
