Description
Summary:This paper presents a novel Swastika-shaped metamaterial structure which exhibits metamaterial behavior (μ- and ε-negative) in distinct frequency ranges. The EM analysis of metamaterial (MTM) structure is carried out using transmission line transfer matrix method and validated with full-wave method based software package. The proposed structure is observed to exhibit bandpass frequency selective characteristics with very good transmission efficiency in the frequency range of 8.5 GHz-10.3 GHz. Further, a planar multilayered radome wall configuration is designed which consists of a thick Arlon layer embedded with Swastika-shaped MTM FSS as the middle layer backed by two thin quartz-based laminations on each side. Further, the thickness of radome wall is optimized sector wise in view of airborne radome applications.
