Negative index materials: at the frontier of macroscopic electromagnetism
Comptes Rendus. Physique, 2020 The notions of negative refraction and negative index, introduced by V. Veselago more than 50 years ago, have appeared beyond the frontiers of macroscopic electromagnetism and purely formal during 30 years, until the work of J.

Effect of Terahertz Electromagnetic Field on the Permeability of Potassium Channel Kv1.2
International Journal of Molecular Sciences, 2023 In this paper, the influence of external terahertz electromagnetic fields with different frequencies of 4 THz, 10 THz, 15 THz, and 20 THz on the permeability of the Kv1.2 voltage-gated potassium ion channel on the nerve cell membrane was studied using the combined model of the “Constant Electric Field-Ion Imbalance” method by molecular dynamics.

The quantum vacuum at the foundations of classical electrodynamics [PDF]
, 2010 In the classical theory of electromagnetism, the permittivity and the permeability of free space are constants whose magnitudes do not seem to possess any deeper physical meaning.

Revista de Matemática: Teoría y Aplicaciones, 2018 Modeling wave reflection and transmission is important for a diversity of applications in physics and engineering. Examples can be found in acoustics and electromagnetism. Computational wave propagation requires high order accuracy both in space and time

Boyer-Lindquist space-times and beyond: Meta-material analogues [PDF]
, 2018 Physically reasonable stationary axisymmetric spacetimes can (under very mild technical conditions) be put into Boyer-Lindquist form. Unfortunately a metric presented in Boyer-Lindquist form is not well-adapted to the "quasi-Cartesian" meta-material ...

Photon Self-Energy in a Color Superconductor [PDF]
, 2001 In a color superconductor the diquark condensates break spontaneously both the color and ordinary electromagnetism, leaving a remanining rotated U(1) symmetry unbroken.

Negative Refraction and Left-handed electromagnetism in Microwave Photonic Crystals [PDF]
, 2004 We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical ...

Dimensions and Units in Electrodynamics [PDF]
, 2004 We sketch the foundations of classical electrodynamics, in particular the transition that took place when Einstein, in 1915, succeeded to formulate general relativity.
