The objective of this report, is to design and simulate an extremely subwavelength negative index metamaterial using CST Microwave studio and achieve a λ/a ratio of greater than 2000.
We simulate a planar single layer spiral, and we introduce a thin wire as a back metal on the other side of the substrate which generates a plasma oscillations. This combination of the spiral structure and the back metal wire, creates simultaneous negative mu and epsilon, which otherwise is called as Negative Index Material. This newly created material resonates at 7.8MHz which gives us a λ/a ratio of nearly 2400. This extremely sub wavelength negative index metamaterial, find application in making super lens, also in medical field and optics.
