ABSTRACT This letter reports numerical and experimental study on a concentric‐edge‐coupled low‐loss MTM structure composed of concentric skewed omega inclusion and capacitive strip wire unit cells for DNG behavior via transmission and reflection characteristics. Modified NRW method provides effective medium parameters, refractive index, and the dispersion characteristic from simulated S‐parameters. It is shown that this MTM exhibits DNG behavior over 3.65–4.53 GHz band. It also investigates the effect of geometrical parameters, like strip width, slit gap, length and width of each side, and arc length on magnetic resonant frequency. Incidence of perpendicularly polarized electromagnetic wave on a host medium embedding metallic skewed omega inclusions interact shows negative material parameters for the composite media in the frequency band of interest. © 2016 Wiley Periodicals, Inc.
