1. An apparatus, comprising:
at least one radio frequency element;
at least one wireless charging coil;
one or more channels disposed between the at least one wireless charging coil and the at least one radio frequency element, wherein a first portion of a respective channel of the one or more channels is at least substantially adjacent to the at least one wireless charging coil and a second portion of a respective channel of the one or more channels is at least substantially adjacent to the at least one radio frequency element;
a dielectric fluid disposed within the one or more channels; and
a processor configured to cause:
triggering a change of magnitude of a magnetic field associated with at least one transmitting coil to initiate movement of the dielectric fluid during wireless charging of the apparatus and leaving the direction of the magnetic field associated with the at least one transmitting coil substantially unchanged.
