1. A wireless charging method comprising:
- transmitting a wireless charging signal;
monitoring at least one of an amplitude and a phase of the wireless charging signal;
determining whether the at least one of an amplitude and phase is within a predetermined range of at least one predetermined value; and
if it is determined that the at least one of an amplitude and phase is not within the predetermined range of the at least one predetermined value, stopping transmission of the wireless charging signal.
