Abstract

We achieve one-dimensional cloaking effects in index-near-zero and epsilon-near-zero metamaterials embedded with just dielectric Bragg-fiber-structured defects. The dielectric Bragg-fiber structure (BFS) within the bandgap region can act as a perfect electric or magnetic conductor which prevents electromagnetic waves from penetrating into the core. As a result, one can hide objects inside the dielectric core without leading large distortion to the transmission. Moreover, both narrow and broad Fano profiles with variations between the total reflections and total transmissions are obtained, corresponding to the core resonances and the BFS resonances, respectively. The conditions of the total reflections and total transmissions are derived. Our work may have potential applications including applications in ultrasensitive sensors and switches.
