Effect of Axial Slit on Metallic Tube for Wireless Power Transfer Via Magnetic Resonance Coupling

—Application of Magnetic-Resonance Coupling Techniques for Infrastructure Diagnostics—

Abstract

Wireless power transfer using a metallic tube with an axial slit was attempted to demonstrate the wireless power transfer using magnetic resonance coupling to the diagnostics infrastructure. The transmission efficiency with variable distance was measured using the transmission and receiver resonators in the tube. Besides, the transmission and receiver resonators were respectively set outside and inside the tube. These experiments are carried out in the computational study using FDTD method.
