Open AccessHigh-permittivity ceramics enabled highly homogeneous zero-index metamaterials for high-directivity antennas and beyond
Zero-index metamaterials (ZIMs) can support uniform electromagnetic field distributions at any frequency, but their applications are hampered by the ZIM’s homogenization level—only 3 unit cells per free-space ...
