Abstract

Several Double Negative (DNG) metamaterials, artificial materials with simultaneous negative permittivity and permeability, have been fabricated and tested experimentally at X-band frequencies. These include a negative index of refraction slab matched to free space and a perfect magnetic conducting slab. The basic concepts of propagation in DNG metamaterials, their designs and experimental verifications will be reviewed. These DNG metamaterials may indeed be very suitable for a variety of electromagnetic applications dealing with guided wave environments, sensors, and antennas. The use of a DNG metamaterial to tailor the propagation characteristics of a microstrip transmission line will be described in detail. It will be demonstrated that a DNG-loaded microstrip transmission line segment that exhibits a negative index of refraction can be matched to an ordinary microstrip line.
