CRLH ZOR metametrial, design, simulation and fabrication

In this article, a survey about ZOR is illustrated and its characteristics are investigated in a detailed manner. The fabrication process has been presented to focus on the practical limitations of metamaterials. An application based on ZOR like a notch filter is presented. The notch filter is used in UWB applications. Later, a tunable mechanism based on the nonlinear dielectric of ferroelectric has been proposed. The model is only simulated due to technology limitations. All different configurations were designed with both HFSS and CST, what resolve the electromagnetic fields in all the structure that is going to be analyzed.
