Abstract :
This paper examines the refractive properties of a wire medium designed to operate in the X-band for directive antenna application. The periodic structure is implemented using 0.5-mm-diameter copper wires arranged on a square lattice with spacing of 10 mm, yielding a cutoff frequency of 7.7 GHz. Through numerical experiments, the refractive index is calculated as n = λ0/λg, where λ0 and λg are the free-space and guided wavelengths, giving an average value of n = 0.6 over the 8-12 GHz frequency range.
