Ultra-Stable Broadband Comb Laser with Tunable Free Spectral Range and Spectra [PDF]

EPJ Web of Conferences
We present a novel near-infrared broadband, flat-top optical frequency comb spanning 1.6 THz. This comb is generated using an interband gain medium operated in an ultrafast gain recovery regime within a unidirectional ring cavity.

Electromagnetic field singularities

Journal of Mathematical Analysis and Applications, 2002
This paper is devoted to the electromagnetic fields with axially symmetric radiating sources. The main goal is to solve the inverse problem by connecting the far-field pattern \(E_\infty: E(r,\theta)= E_\infty (\theta) {e^{ir} \over r}+0({1\over r^2})\) for large \(r\) with \(E\)-field singularities.

Large Area, Cost‐Effective, and Ultra‐Fast Fabrication of Mini‐Coils Toward Noninvasive Magnetic Applications

Advanced Engineering Materials, EarlyView.
A simple, cleanroom‐free method produces flexible mini‐coils using automated blade cutting. The process is fast, low‐cost, and supports diverse materials. The coils show strong durability and performance under repeated bending. Demonstrated use in resistor‐inductor filters and magnetic nanoparticle control proves their adaptability.

Particle Production in Strong Electromagnetic Fields in Relativistic Heavy-Ion Collisions [PDF]

, 2013
I review the origin and properties of electromagnetic fields produced in heavy-ion collisions. The field strength immediately after a collision is proportional to the collision energy and reaches ~ at RHIC and ~ at LHC.

Spacetimes dressed with stealth electromagnetic fields

, 2018
Stealth field configurations by definition have a vanishing energy-momentum tensor, thus do not contribute to the gravitational field equations. While only trivial fields can be stealth in Maxwell's electrodynamics, nontrivial stealth fields appear in ...

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

Advanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

Neutron Acceleration in Uniform Electromagnetic Fields

, 1993
The question as to whether neutron acceleration can occur in uniform electromagnetic fields is examined. Although such an effect has been predicted using the canonical equations of motion some doubt has been raised recently as to whether it is in ...
