Genetically engineered multiband high‐impedance frequency selective surfaces

Abstract

Abstract A methodology is presented for the design synthesis of metamaterials that act as thin multifrequency artificial magnetic conductors. These structures are realized by placing a frequency‐selective surface above a conventional prefect electric conductor, separated by a thin dielectric layer. The frequency‐selective surface design is optimized using a micro‐genetic algorithm to operate at multiple, narrow frequency bands. Two examples of genetically engineered multiband high‐impedance frequency‐selective surfaces (that is, artificial magnetic conductors) are presented and discussed. © 2003 Wiley Periodicals, Inc.
