Equivalent circuit analysis for 3D metamaterials with fringing field correction factor WhittakerTom WhittowWilliam VardaxoglouJ. C. 2019 © 2017 Institution of Engineering and Technology. All rights reserved. This paper presents a fringing field correction factor for circuit modelling techniques of metasurfaces and metamaterials. The theory is then applied to periodic three dimensional metamaterial meta-atoms. Equivalent circuits have been validated using CST Microwave Studio.
