    A wideband ENG meta-atom for microwave applications
    (CRP, International Islamic University Chittagong, 2023-12) Islam, Sikder Sunbeam
    Effective medium ratio (EMR) is an important parameter for a meta-atom for ensuring its emerging performance those not naturally available. This paper depicts an effective medium obeying new meta-atom that shows epsilon negative (ENG) property in the wideband region of microwave electromagnetic regime. Initially, the simple basic unit cell (atom) structure was designed on Rogers RT6010 substrate material that displays nearly 3 GHz epsilon negative property with good effective medium ratio (EMR). The structure shows better performance with more than 3GHz ENG property with better EMR in the microwave region when it was designed on FR-4 substrate material. A material with good ENG property can be utilized in many important electromagnetic applications. Finite integration technique-based CST microwave studio software was used to investigate the characteristics of the unit cell. The simple construction, good EMR and wide band ENG property has made the design significant for the electromagnetic microwave operations.
