A microwave metamaterial with integrated power harvesting functionality
Abstract
We present the design and experimental implementation of a power harvesting metamaterial.
A maximum of 36.8% of the incident power from a 900 MHz signal is experimentally rectified
by an array of metamaterial unit cells. We demonstrate that the maximum harvested
power occurs for a resistive load close to 70 Ω in both simulation and experiment.
The power harvesting metamaterial is an example of a functional metamaterial that
may be suitable for a wide variety of applications that require power delivery to
any active components integrated into the metamaterial. © 2013 AIP Publishing LLC.
