1. A system comprising:

  • a processor;

    a plurality of resonant tags, wherein each resonant tag further comprises;

    a cylindrical array comprising a plurality of structures arranged to form a second hollow cylinder;

    a dielectric material configured to fill the second hollow cylinder; and

    a binder configured to adhere the filled cylindrical array to a borehole-facing wall for a well casing; and

    an interrogator configured to interrogate a channel associated with an oil well borehole between the interrogator and the resonant tags adhered to the borehole-facing wall using a frequency-modulated radio frequency (RF) signal such that the frequency-modulated RF signal covers an expected range of resonant frequencies for the resonant tags within the channel, and wherein the processor is configured to characterize a dielectric constant for a medium in the channel using resonant reflections received by the interrogator from the resonant tags in the channel.
