In this paper we study the electromagnetic scattering, absorption, and performance bounds
for short time modulated pulses that impinge on a time-varying lossy layer that is …

Non-Hermitian theory, originated from quantum mechanics, is a theoretical framework for
investigating the dynamics of open systems. New phenomena can be revealed with this …

We propose a scheme to obtain highly sensitive oscillators in a coupled-resonator system
with an exceptional point of degeneracy (EPD) and a small instability. The oscillator with the …

The interaction between a linear electron beam and a guided electromagnetic wave is
studied in the context of exceptional points of degeneracy (EPD) supported by such an …

Wireless, battery-free body area networks (BANs) enable reliable long-term health
monitoring with minimal intervention, and have the potential to transform patient care via …

We present the experimental demonstration of the occurrence of exceptional points of
degeneracy (EPDs) in a single resonator by introducing a linear time-periodic variation of …

The recently developed concept of time-varying metamaterials paves the way for advanced
methods of electromagnetic property modulation, such as magnet-free isolators, frequency …

We demonstrate how exceptional points of degeneracy (EPDs) are induced in a single
transmission line (TL) directly by applying periodic space–time modulation to the per-unit …

We study the rise of exceptional points of degeneracy (EPD) in various distinct circuit
configurations such as gyrator-based coupled resonators, coupled resonators with PT …

We demonstrate that a circuit comprising two unstable LC resonators coupled via a gyrator
supports an exceptional point of degeneracy (EPD) with purely real eigenfrequency. Each of …
