In the letter, we propose the design of circulators based on spoof surface plasmon polaritons (SSPP). Rather than striplines, the center conductor is replaced with a blade structure that supports the SSPP mode and exhibits a shorter wavelength and larger wave vector. To enhance the efficiency, a matching transition is employed between the coplanar waveguide and the blade structure. With biased ferrites...
In this letter, magnetless reciprocal metamaterials are used to realize the circulation performance in free space. The metamaterials we used in the paper are ideal phase gradient metasurfaces, which is realized by different materials with different index of refraction. The anomalous refraction feature of the phase gradient metasurface is utilized to realize circulation characteristics. In free space,...
This paper shows a study of a new kind of circulator with spoof surface plasmon polaritons (SSPPs). In this letter, the combination of SSPPs and Y-junction in inner conductor is in consideration. SSPPs transmission mode and TEM mode is dominant in different band. That makes the broadband characteristic of the circulator. The structure is optimized in HFSS for better performance. From 4.5 GHz to 13...
