Controlling Electromagnetic Fields [PDF]

open access: yesScience, 2006
Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...

Pseudo-electromagnetic fields in 3D topological semimetals [PDF]

open access: yesNature Reviews Physics, 2019
Dirac and Weyl semimetals react to position-dependent and time-dependent perturbations, such as strain, as if subject to emergent electromagnetic fields, known as pseudo-fields.

Charged particle motion and radiation in strong electromagnetic fields [PDF]

open access: yesReviews of Modern Physics, 2021
The dynamics of charged particles in electromagnetic fields is an essential component of understanding the most extreme environments in our Universe. In electromagnetic fields of sufficient magnitude, radiation emission dominates the particle motion and ...

Test setup using DC metering approach for loss measurements of inductive components – principle, characterization, validation and application

open access: yesIET Power Electronics, 2021
Accurate loss estimation of magnetic components is crucial for power electronics engineers. Unfortunately, loss predictions remain a quite challenging task, as these depend on many parameters and manufacturers typically do not deliver a sufficient ...

Guidelines for Limiting Exposure to Electromagnetic Fields (100 kHz to 300 GHz).

open access: yesHealth Physics, 2020
Radiofrequency electromagnetic fields (EMFs) are used to enable a number of modern devices, including mobile telecommunications infrastructure and phones, Wi-Fi, and Bluetooth. As radiofrequency EMFs at sufficiently high power levels can adversely affect

Plasmonic, photonic, or hybrid? Reviewing waveguide geometries for electro-optic modulators

open access: yesAPL Photonics, 2023
Electro-optic modulators are key elements in high-speed optical telecommunication links and preferably rely on materials with a linear electro-optic effect.
