Controlling Electromagnetic Fields [PDF]
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]
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]
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 ...

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