Abstract :
We present the feasibility and optimization of wireless powering of sensors embedded in concrete that relies on a plane wave propagation model. Transmission loss and propagation loss of RF wave penetrating into concrete at different humidity conditions are calculated for various frequencies. An optimum frequency range within 20-80 MHz is identified for the wireless power transmission and is validated through antenna coupling full-wave EM simulations. The effects of reinforced bars to the propagation of RF power are also analyzed.
