Downhole power and data transfer using resonators

摘要

A downhole system usable with a well string is provided that can include a first resonator positioned on the well string. The system can also include a second resonator positioned to couple with the first resonator by an evanescent field. The second resonator can include a load. Further, the system can include a metamaterial positioned between the first resonator and the second resonator for amplifying or extending a range of the evanescent field.
