摘要

The application of high-frequency electromagnetic (EM) waves for line-of-sight wireless power transfer (WPT) is well established. However, the short wavelength necessary for high power density complicates transmission through barriers. Furthermore, high-power EM radiation in air presents safety concerns. Waveguides can channel waves or directed beams over long distances through barriers. The challenges with typical waveguides include cost, adaptability, losses at bends and junctions and posing barriers to personnel. In order to mitigate these challenges, especially at the waveguide bends and junctions, the waveguide material properties should be optimized. Metama-terials provide the opportunity to realize certain combinations of electromagnetic material properties that are not found in nature, the most compelling example being negative and near-zero indexes of refraction. These properties could allow high-power energy transmission through waveguides while minimizing cost, improving the adaptability of the system, and improving the efficiency at bends and junctions. A metamaterial waveguide consisting of a combination of shape primitives (or, alternatively, a single contiguous channel), each with their own optimized parameters for the transmission frequency, could deliver high power density safely and efficiently. This conceptual study investigates the feasibility of implementing a metamaterial waveguide to channel high-power EM energy with minimal losses and increased adaptability.
