Magnetic Nature of Light Transmission through a 5-nm Gap
Scientific Reports, 2018 Slot antennas have been exploited as important building blocks of optical magnetism because their radiations are invoked by the magnetic fields along the axes, as vectorial Babinet principle predicts.

The World Wide Lightning Location Network (WWLLN) over Spain [PDF]
Natural Hazards and Earth System SciencesThe World Wide Lightning Location Network (WWLLN) operates a distributed network of stations which detect lightning signals at a planetary scale. Very high currents from lightning strokes radiate strong very low frequency signals in the 6–22 kHz band ...

Quantum Einstein-Maxwell Fields: A Unified Viewpoint from the Loop Representation [PDF]
, 1992 We propose a naive unification of Electromagnetism and General Relativity based on enlarging the gauge group of Ashtekar's new variables. We construct the connection and loop representations and analyze the space of states.

Canonical quantization of macroscopic electromagnetism [PDF]
, 2010 Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption.

Networks & Heterogeneous Media, 2010 The electromagnetic analog of an elastic spring-mass network is constructed. These electromagnetic circuits offer the promise of manipulating electromagnetic fields in new ways, and linear electrical circuits correspond to a subclass of them. They consist of thin triangular magnetic components joined at the edges by cylindrical dielectric components ...

Multiobjective-Optimized Design of a New UWB Antenna for UWB Applications
International Journal of Antennas and Propagation, 2013 A multiobjective genetic algorithm has been applied to design a new printed, bow-tie antenna for ultrawideband applications, that is, ground penetrating radar, short range and high data rate communications, and so forth.

Angstrom-Scale Active Width Control of Nano Slits for Variable Plasmonic Cavity
Nanomaterials, 2021 Nanogap slits can operate as a plasmonic Fabry–Perot cavity in the visible and infrared ranges due to the gap plasmon with an increased wavenumber. Although the properties of gap plasmon are highly dependent on the gap width, active width tuning of the ...

Covariant jump conditions in electromagnetism [PDF]
, 2014 A generally covariant four-dimensional representation of Maxwell's electrodynamics in a generic material medium can be achieved straightforwardly in the metric-free formulation of electromagnetism.

Electromagnetic Radiation* [PDF]
, 1999 Electromagnetic radiation, commonly referred to as light, underpins all spectroscopic techniques, ranging from the highly energetic gamma rays, through x-rays, ultraviolet, visible, infrared, microwaves to the low-energy radio waves. The principles of wave- and particle-like behaviour determine the nature of the radiation and its interaction with ...
