Abstract
Systems, apparatuses, and methods are provided for producing a directional electric field from an end of the solenoid in an efficient manner. For example, voltage pulses can be used to charge the turns of the coil so that the coil acts as a capacitor. The voltage pulses can be of a specified time width (e.g., 1 μs or less) so as to reduce the amount of current flowing in the coil, and thus reduce the input power used in the coil. The electric field can be used for a variety of purposes, e.g., for charging or communication. An output conductor can be positioned such that electrons can be moved in the output conductor. The motion of electrons can correspond to the communication of data or be used to operate a load (e.g., in charging a device or otherwise providing power).
