| Popis: | In this article X-band rectangular waveguides partially filled with the double-side single ring resonator (DSRR) array are investigated for miniaturization, stop-band, and multi-band filters applications. Several rectangular waveguides loaded with the DSRR array in 2–10 GHz frequency band have been studied and optimized. We observe both the transversal negative permeability presented above the cutoff frequency and the backward-wave located below the cutoff frequency with the DSRR array in X-band waveguide. Both simulation and measurement results of DSRR array are with good agreement. The DSRR array provides better performance of the transversal negative permeability and the backward-wave than the split-ring resonator array. The physical explanation of backward-wave is presented. The power loss distributions are clearly presented for the negative permeability attenuation and the backward-wave propagation. © 2016 Wiley Periodicals, Inc.
