(Color online) Geometry of examples of MNG materials: (a) Multisplit ring resonator with side length and number of rings ; (b) multisplit ring resonator with , ; (c) spiral resonator with and number of turns .
(Color online) Experiment setup (photo). The polarization of the incident wave is also shown.
(Color online) Experimental transmission data as a function of the frequency. (a) Multisplit ring resonators with the side length . (b) Multisplit ring resonators with the side length . (c) Spiral resonators with the side length .
(Color online) Resonance frequency as a function of the number of rings and turns (experiment and simulation).
Comparison of the MNG materials in the literature in terms of electrical size , resonance frequency , and radius of the minimum sphere . The free space wavelength is denoted as . (Capacitance loaded is abbreviated as C.L.) The exact numbers of rings (turns) given in the last three columns are for the MSRR structures and for the SR structure.
