Design of a novel single-layer dual-band FSS with angular stability using multifractal geometry

A novel single-layer dual-band FSS with angular stability is proposed in this paper. The proposed FSS is a junction of the Koch curve with the Ericampos multifractal geometry. The FSS functioning as stop band filter for satellite application at S-and X-Bands. The proposed FSS exerts high angular stability and the same response for both TE and TM operation modes because of its inherent symmetry. The validation of the proposed structure was verified through measurements. A good agreement between numerical and experimental results is obtained.
