Abstract Negative‐permeability sub‐wavelength particles, namely split‐ring resonators and spiral resonators, are compared and their performances analyzed for a different number of concentric rings and spiral turns, respectively. Left‐handed lines are designed, fabricated, and measured that use multiple complementary split‐ring and spiral resonators. More compact structures are obtained, with improved characteristics. © 2007 Wiley Periodicals, Inc.
