Abstract :
The feasibility of efficient wireless power transfer through Strongly Coupled Magnetic Resonance (SCMR) in non-homogenous interface such as air-concrete is studied here. Specifically, the efficiency of wireless power transmission from a source in air to a sensor embedded in concrete via strongly coupled magnetic resonance is analyzed. The concrete material is modeled for various humidity levels using the extended Debye´s model. The efficiency of the SCMR is also analyzed for various depths inside the concrete.
