Anomalous electron energy loss in small spheres

Journal of Physics C: Solid State Physics, 1983
In analogy to the case of optical absorption it is shown that inclusion of nonlocal surface effects results in a very large contribution to the energy loss of fast electrons scattered by a sphere. The scattering is found to be predominantly in the forward direction and is an order of magnitude larger than that calculated classically.

The causes of the anomalous loss in amorphous ribbon materials

IEEE Transactions on Magnetics, 1981
The total power loss under alternating flux at power frequencies and zero applied stress conditions is an important criterion for the manufacturer and user of soft magnetic materials. The total power loss may be divided into three major types, namely the static hysteresis loss, classical eddy current loss and excess eddy current loss. It has been shown

A fractal model of anomalous losses in ferromagnetic materials

PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003
A simple fractal, or hierarchical, circuit model is presented which simulates the anomalous loss behavior in ferromagnetic materials as a function of frequency and peak flux density. According to this model, the anomalous losses comprise a cascade of scaling eddy current losses. The terminal voltage and current of this model are related by a fractional

Anomalous Energy Loss of Electrons in Ferroelectrics at the Curie Temperature

Physical Review Letters, 1982
Experimentally it is found that the energy loss of 620- and 942-keV electrons in barium titanate, as well as that of 942-keV electrons in triglycine sulphate, is anomalously high at the Curie temperature. The energy loss is also noticeably smaller in the ferroelectric state than in the paraelectric state.

The Barkhausen Effect and the Anomalous Magnetization Losses in Metallic Ferromagnets

Czechoslovak Journal of Physics, 2004
The aim of this work is calculation of the contribution of the irreversible domain wall shifts to the total remagnetization losses. It has been shown that the irreversible remagnetization losses are approximately 2.4 times higher in comparison with the reversible one.

Anomalous loss scaling in periodically absorbing media

Journal of the Optical Society of America B, 2001
The scaling of the transmission, absorption, and reflection properties of periodically absorbing media consisting of alternating lossy and lossless layers are studied as a function of the number of periods. These studies show that, at the structure transmission resonances, distributed loss—defined through both attenuation and absorption per unit length—

Anomalous, intensity dependent losses in Au(32+) beams

Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002
Anomalous, intensity dependent losses in Au(32+) beams have been observed in the AGS Booster. No collective signal is expected, or observed, but increasing the number of injected ions decreases the beam lifetime. The loss rates for Au(32+) are compared with those for Au(15+).

Anomalous increments of AC losses due to flux jumps

IEEE Transactions on Magnetics, 1977
AC losses are measured applying magnetic fields of frequencies from 8.6 to 75 Hz and of 3 kG peak values to wires of Nb-60.2Ti-2.8Zr alloy mounted in slots of a bakelite bobbin. The temperature is varied between 1.9 K and the superconducting transition temperature T c = 8.9 K using supercritical He as coolant for the higher temperature region ...

Digital Twin-based Insertion Loss Estimator for Anomalous Loss Localization and Network Equalization Enhancement

Optical Fiber Communication Conference (OFC) 2024
We propose and experimentally validate a novel accurate digital-twin-based span-level insertion losses estimator. This enables detection and localization of anomalous insertion losses; when combined with equalization, 1.3dB SNR margin improvement is demonstrated despite inaccurate physical layer knowledge.
