Abstract Radio Frequency Identification (RFID) technology is considered as a new sensing
paradigm due to its low-cost, passive wireless power transfer capability, flexibility, and non …

Exceptional points are spectral singularities in open quantum and wave systems that exhibit
a strong spectral response to perturbations. This feature can be exploited for a new …

Exceptional points are degeneracies in physical systems at which both the underlying
eigenvalues and eigenvectors of the system coalesce. They originated in theoretical …

We demonstrate the transient parity-time (PT) symmetry in electronics. It is revealed by
equivalent circuit transformation according to the switching states of electronic systems. With …

Parity–time (PT) symmetry challenges the long-held theoretical basis that only Hermitian
operators correspond to observable phenomena in quantum mechanics. Non-Hermitian …

Graphene biosensors have received more and more attention over the past two decades in
the modern fields including labeled, and label-free sensing owing to their ability to harness …

Standard exceptional points (EPs) are non-Hermitian degeneracies that occur in open
systems. At an EP, the Taylor series expansion becomes singular and fails to converge—a …

Achieving extraordinarily high sensitivity is a long-sought goal in the development of novel
and more capable electromagnetic sensors. We present here how a coherent perfect …

A fundamental challenge for the nonradiative wireless power transfer (WPT) resides in
maintaining the stable power transmission with a consistently high efficiency under dynamic …

Recent developments in non-Hermitian physics offer exciting opportunities for a broad range
of basic research and engineering applications relevant to the antennas and propagation …
