1. A wireless power transmitter comprising:
- a generator configured to generate a power;
a resonator configured to generate a magnetic field to transmit the power to a target device; and
a slab unit configured to enhance the magnetic fieldwherein the slab unit comprisesa metamaterial comprising an electric dipole structure and a magnetic dipole structure,wherein a relative permittivity at the metamaterial is determined based on the electric dipole structure and a relative permeability of the metamaterial is determined based on the magnetic dipole structure,wherein the magnetic dipole structure comprises a loop-shaped conductor configured to generate a capacitance associated with a resonance characteristic and wherein the capacitance is determined to have a zeroth order resonance for the resonator at a target frequency of transmitting the power.
