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.
