Parity-time (PT) symmetry has recently been opening exciting directions in photonics, yet the
required careful balance of loss and gain has been hindering its widespread applicability …

The development of the next generation of wireless systems is bringing renewed attention to
the physical layer of the communication link. Indeed, the new low-latency requirements …

Nonradiative wireless power transfer (WPT) technology has made considerable progress
with the application of the parity-time (PT) symmetry concept. In this Letter, we extend the …

Topological characteristics, including invariant topological orders, band inversion, and the
topological edge mode (TEM) in photonic insulators, have been widely studied. Whether …

We show that, by using a saturable gain g sat, generalized PT (GPT) symmetry can be
achieved in the intrinsically unbalanced (non-PT-symmetric) high-order wireless power …

Electromagnetic resonators are a versatile platform to harvest, filter, and trap
