Article Title: A New Design of SRR Operating at Microwave Bandwidth, Parametric Study
by A. Qarchi, H. Belkebir, A. Mir, A. Bouzid

Abstract:
The magnetic resonators commonly called SRR are structures that exhibit a high frequency magnetic activity where natural magnetism disappears completely. Theses resonant structures with a frequency range where the permeability is negative when inserted into a metal rods network that has a frequency range where the permittivity is negative give rise to some particular physical phenomena such as the inversion of the Doppler and Cerenkov effects, and also a medium with negative refraction index, the problem that often occurs is the overlapping frequency ranges, which is not always obvious. In this work, we will present a new shape of SRR that have an artificial magnetism behavior. We will show numerically in a parametric study one of the techniques which provide us the possibility to control the frequency response and hence to tune the negative bandwidth to meet need of the overlapping ranges. The losses by absorption are investigated. The effective parameters are calculated using the transfer matrix and Fresnel coefficients method.
Keywords: split ring resonator, metamaterials, negative refraction index, effective parameters.
