Abstract
In this work, a patch-type WPT system using EM wave focusing
metasurface is presested. A subwavelength-thickness (< λ/10) metasurface that focuses electromagnetic waves to a
desired depth in multilayered biological tissues to enhance the transferred power of WPT system for implantable
devices. We demonstrated the stable focusing performance of the proposed metasurface patch by confirming the
fixed focal point and field intensity profiles for oblique incident angles up to 30°.
