Abstract
A transmit resonator is provided. The transmit resonator comprises: at least two inductors; at least one switching network electrically connected to one inductor of the at least two inductors; at least one secondary capacitive electrode electrically connected to the switching network; at least one main capacitive electrode electrically connected to one inductor of the at least two inductors; and a controller electrically connected to the switching network. The controller is configured to control the switching network to control connection of the secondary capacitive electrode to one inductor of the at least two inductors via the switching network. The inductors and electrodes are configured to resonate to generate an electric field.
