Zero-Pole Optimization of a Novel High-Quality-Factor Planar Helical Resonator

open access: yesMagnetism, 2023
A novel micro-solenoid resonator has been designed, simulated, and measured. The solenoid core consisted of a DuroidTM circuit board with a relative permittivity of 2.2.

Impulse Magnetized Magnetic Screws [PDF]

open access: yesIEEE Transactions on Magnetics, 2019
This paper is an investigation in the performance of two types of magnetic screws (MSs). The first is the magnet to magnet and consists of permanent magnet (PM) nut and PM screw and the second is a magnet to reluctance and consists of PM nut and a double-start reluctance screw.

Magnetic Catalysis Versus Magnetic Inhibition [PDF]

open access: yesPhysical Review Letters, 2013
We discuss the fate of chiral symmetry in an extremely strong magnetic field B. We investigate not only quark fluctuations but also neutral meson effects. The former would enhance the chiral-symmetry breaking at finite B according to the Magnetic Catalysis, while the latter would suppress the chiral condensate once B exceeds the scale of the hadron ...

Magnetic Field as an Important Tool in Exploring the Strongly Correlated Fermi Systems and Their Particle–Hole and Time-Reversal Asymmetries

open access: yesMagnetism, 2023
In this review, we consider the impact of magnetic field on the properties of strongly correlated heavy-fermion compounds such as heavy-fermion metals and frustrated insulators with quantum spin liquid. Magnetic field B can be considered a universal tool,

Low-Frequency Dynamic Magnetic Susceptibility of Antiferromagnetic Nanoparticles with Superparamagnetic Properties

open access: yesMagnetism, 2022
As is known, the multi-sublattice structure of antiferromagnets (AFMs) entails that, under size diminution to the nanoscale, compensation of the sublattice magnetizations becomes incomplete.

Numerically Stable and Computationally Efficient Expression for the Magnetic Field of a Current Loop

open access: yesMagnetism, 2022
In this work, it is demonstrated that straightforward implementations of the well-known textbook expressions of the off-axis magnetic field of a current loop are numerically unstable in a large region of interest.

Electromagnetic Tracking of Elongated Sensors for Endoscopic Navigation

open access: yesMagnetism, 2022
As the prevalence of image-guided interventions increases, electromagnetic tracking (EMT) systems play an important role in modern patient care, as they enable real-time instrument positioning and navigation inside the human body without line-of-sight ...
