... In 1996, Pendry introduced the first fabricated medium (composed of wire), which has a negative value of permittivity [3,4]. In 1999, Pendry proposed the magnetically responded artificial medium, called, Split Ring Resonator (SRR), which has a negative permeability [3,5]. The first left handed medium (ε<0, µ<0) was achieved by Smith et al. in 2001 by using the combination of wires and Split Ring [3,6]. ...
Advanced materials are artificial structure materials that exhibit properties not found in nature. Material that has a negative refractive index (left-handed materials) is found to get a lot of interest in the literatures. Controlling the geometry of classical material may lead to have a negative refractive index in a certain frequency range. In this paper, we utilized from fractal geometry in our design. A Sierpinski Carpet fractal model is proposed. Calculations show that this model has a negative refractive index in the frequency range 7.5 GHz – 16.5 GHz. Wide band behavior of this model refers to its fractal shape.
