“…On the other hand, a metamaterial with near-zero properties can be used in the structure of a near-zero lens, which in turn can be used as a near-zero superstrate for planar antennas. According to the Snell's law, when a near-zero media is placed over a positive index media, the electromagnetic rays exiting from the whole system become closer to each other compared to the case when there is no near-zero media [9]. This feature can be used as a gain-enhancement technique for antenna applications.…”

In this paper, the design and simulation of a new metamaterial unit-cell is presented. The proposed unit-cell is based on the concept of fractals and also takes advantage of having a reconfigurable structure. Two PIN diodes are embedded in the unit-cell so it can be switched between two different modes, providing a reconfigurable feature. The S parameters of the structure in both modes are simulated using CST Microwave studio and then a well-known algorithm is used to extract the effective permittivity and permeability. According to the simulation results, this structure demonstrates two different behaviors for permittivity and permeability in each state of the diodes. The unit-cell will be used for microwave applications, such as agile lens antennas with reconfigurable pattern properties.
