Abstract
A transmitter comprises a power source; a transmit resonator electrically connected to the power source via an electrically small transmission line; and a metamaterial transmission line (MMTL) electrically connected between the power source and the electrically small transmission line. The transmit resonator comprises at least two electrodes; and at least one inductive coil electrically connected to the electrodes. The transmit resonator is configured to generate an electric field when excited by the power source. The electrically small transmission line is shorter in length than a wavelength of excitation of a power signal generated by the power source. The MMTL is configured to counteract an effect of the electrically small transmission line. The MMTL has a negative phase velocity (NPV).
