Abstract :
In this paper, new artificial magnetic materials based on fractal Hilbert curves are proposed, modeled and numerically analyzed. It is shown that using fractal structures as inclusion in the design of artificial magnetic materials allows miniaturization of the unit cell size, thus enabling design of miniaturized devices such as antennas. Furthermore it is proven analytically and numerically that these new materials are less dispersive in comparison to conventional split rings
