1. A method comprising:
detecting a noise level of radiofrequency noise interacting with an electromagnetic radiofrequency noise recipient in a computing device, wherein the computing device further includes an electromagnetic radiofrequency noise source emitting at least a portion of the radiofrequency noise and a resonant circuit including a capacitive element and an inductive element, wherein the inductive element includes primary inductor rings positioned in proximity to a modulation ring;
determining that the detected noise level satisfies an interference condition; and
tuning a radiofrequency bandwidth at which the resonant circuit resonates by modulating electrical current supplied to the modulation ring of the inductive element in the resonant circuit, based at least on determining that the detected noise level satisfies the interference condition.
