Abstract

Electric permittivity and magnetic permeability control electromagnetic wave propagation through materials. In naturally occurring materials, these are positive. Artificial materials exhibiting negative material properties have been reported: they are referred to as metamaterials. This paper concentrates on a ring-type split-ring resonator (SRR) exhibiting negative magnetic permeability. The design and synthesis of the SRR using the genetic-algorithm approach is explained in detail. A user-friendly graphical user interface (GUI) for an SRR optimizer and estimator using MATLAB™ is also presented.
