Decomposition of Electromagnetic Interferences in the Time-Domain [PDF]
IEEE Transactions on Electromagnetic Compatibility, 2016 Electromagnetic interferences are potentially very complex signals formed by the superposition of transient (broadband) and continuous wave (narrowband) components with significant randomness in both amplitude and phase. Decomposing the electromagnetic interference measured in the time domain into a set of intrinsic mode functions is useful to gain ...

Electromagnetic signatures of far-field gravitational radiation in the 1+3 approach [PDF]
Class. Quantum Grav. 32, 015011 (2015), 2014 Gravitational waves from astrophysical sources can interact with background electromagnetic fields, giving rise to distinctive and potentially detectable electromagnetic signatures. In this paper, we study such interactions for far-field gravitational radiation using the 1+3 approach to relativity.

Electromagnetic Interference in RIS-Aided Communications [PDF]
arXiv, 2021 The prospects of using a reconfigurable intelligent surface (RIS) to aid wireless communication systems have recently received much attention. Among the different use cases, the most popular one is where each element of the RIS scatters the incoming signal with a controllable phase-shift, without increasing its power.

Energy Transfer and Interference by Collective Electromagnetic Coupling [PDF]
Nano Letters, 2019 The physics of collective optical response of molecular assemblies, pioneered by Dicke in 1954, has long been at the center of theoretical and experimental scrutiny. The influence of the environment on such phenomena is also of great interest due to various important applications in e.g. energy conversion devices. In this manuscript we demonstrate both
