Dual-polarized band-stop FSS spatial filters using vicsek fractal geometry



This article presents a fractal design methodology for frequency selective surfaces (FSSs) by printing a finite planar array of Vicsek fractal metallic patches on a single dielectric layer. Shapes presented by the Vicsek fractal as a function of the fractal parameters (level and scale factor) were exploited to design FSSs acting as dual-polarized band-stop spatial filters for incident plane waves. Transmission properties of these FSSs were analyzed and two FSS prototypes were built and measured to validate the fractal design methodology. The obtained results pointing to interesting FSS properties: a high frequency compression factor of 50.31% and stable resonance frequency at oblique incidence. © 2012 Wiley Periodicals, Inc.
