Abstract
At least some aspects of the present disclosure feature an RF device including a conductive loop and a plurality of resonant circuits. Each of the plurality of resonant circuits is electromagnetically coupled to the conductive loop with an effective coupling coefficient. The effective coupling coefficient has a relative low absolute value such that each of the plurality of resonant circuits has a distinctive resonant frequency.
