Broadening the Bandwidth of Epsilon-Near-Zero Metamaterials with Embedded Square Frames
A narrow frequency bandwidth of epsilon-near-zero metamaterials limits the use of many optical, microwave, and electronic devices. In this paper, we propose a recipe to broaden the operational bandwidth by employing a structure of properly tailored square frames nested within each other. To illustra...
