Lightning electromagnetic fields (LEMFs) are complex, multi-component signals generated during a lightning discharge that propagate through the atmosphere and into the ground. Their ...

A new publication in Opto-Electronic Science discusses forbidden propagation of hyperbolic phonon polaritons and applications in near-field energy transport.

Nov. 16, 2022 — Researchers have discovered new waves with picometer-scale spatial variations of electromagnetic fields which can propagate in semiconductors like ...

Electric and magnetic field boundary conditions. Week 8 Application of the time-dependent Maxwell’s curl equations to plane-wave propagation in free space. Power flow in the electromagnetic field.

In the near field, separate E and H component measurements are indispensable, and they significantly complicate the issue of the S measurement. • The EMF polarization in the near field, especially in ...

The researchers experimentally mapped the toroidal electromagnetic pulses at propagation distances of 5, 50 and 100 cm from the horn aperture, using a planar microwave anechoic chamber (a shielded ...

Engineers have succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply.

Light, ever so familiar, remains one of the greatest mysteries of science. From Newton to Einstein to the present, there much we know and still don't know.

It’s hard to imagine life without mobile phones, radio and television. Yet the discovery of the electromagnetic waves that underpin such technologies grew out of an abstract theory that’s 150 ...
