Abstract
Magnetic-Free Plasmonic Isolation A reconfigurable non-magnetic isolator based on parametric amplification is demonstrated experimentally on an ultrathin planar spoof plasmonic platform in article number 2100578. Xinxin Gao, Jingjing Zhang, and colleagues envision this work can establish a foundation for developing magnetic-free non-reciprocal devices suitable for on-chip integration with microwave circuits, with high potential to miniaturize existing communication and radar systems.
