On rational electromagnetic fields [PDF]
Physics Letters A, 2020 We employ a recently developed method for constructing rational electromagnetic field configurations in Minkowski space to investigate several properties of these source-free finite-action Maxwell ("knot") solutions. The construction takes place on the Penrose diagram but uses features of de Sitter space, in particular its isometry group. This admits a

Conserved charges for rational electromagnetic knots
The European Physical Journal Plus, 2022 AbstractWe revisit a newfound construction of rational electromagnetic knots based on the conformal correspondence between Minkowski space and a finite $$S^3$$ S 3 -cylinder.

A new construction of rational electromagnetic knots [PDF]
Proceedings of Corfu Summer Institute 2018 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2018), 2018 We set up a correspondence between solutions of the Yang-Mills equations on R×S3 and in Minkowski spacetime via de Sitter space. Some known Abelian and non-Abelian exact solutions are rederived. For the Maxwell case we present a straightforward algorithm to generate an infinite number of explicit solutions, with fields and potentials in Minkowski ...

Electromagnetic Transient Analysis of Transmission Line Based on Rational Krylov Approximation [PDF]
IEEE Transactions on Power Delivery, 2021 This paper shows a comparison between Vector fitting and rational Krylov fitting techniques for the determination of rational models concerning the fitting accuracy, the computational performances and the model order. Primarily, the mathematics behind the second technique are presented.

Adaptive optics imaging of the retina
Indian Journal of Ophthalmology, 2014 Adaptive optics is a relatively new tool that is available to ophthalmologists for study of cellular level details. In addition to the axial resolution provided by the spectral-domain optical coherence tomography, adaptive optics provides an excellent ...
