Demagnetizing factors for completely shielded rectangular prisms

Journal of Applied Physics, 2004
Fluxmetric and magnetometric demagnetizing factors Nf and Nm have been calculated using a finite-element method for rectangular prism 2a×2b×2c with susceptibility χ=−1, in the completely shielded state. Assuming the field is applied along the c dimension, the results are plotted and tabulated as functions of their aspect ratios c∕a and b∕max[c,a].

Atomic shielding factors for nuclear moments

Zeitschrift f�r Physik, 1967
Atomic shielding factors describe the effect of a deformation of the electron core on the hyperfine structure, which is important for the spectroscopic determination of nuclear moments. For the quadrupole moment they are known as Sternheimer corrections. Such shielding factors for free atoms are discussed in the picture of configuration interaction for

Quadrupole Anti-Shielding Factor in Copper

Nature, 1959
RECENT measurements of the nuclear magnetic resonance absorption line in heavily deformed copper sheet1 showed that, although the plastic deformation caused some reduction in the intensity of the line, this reduction was only one-third of that predicted by Bloembergen2 on the basis of nuclear quadrupole interactions; furthermore, there was no apparent ...

Charts for estimating the axial shielding factors of open-ended cylindrical shields

IEEE Transactions on Magnetics, 1999
Axial shielding factors of single and double-shell open-ended cylindrical magnetic shields are calculated numerically and represented by charts. It is assumed that the thickness of the shells is small (1%) compared to the largest diameter and the permeability is independent of magnetic induction.

The Filling Factor of Shielded Dielectric Resonators

IEEE Transactions on Microwave Theory and Techniques, 1969
The use of dielectric resonators at microwave frequencies usually requires a shield to prevent loss of energy by radiation, and a coupling network. The efficiency of a given circuit depends on the filling factor, which expresses the circuit ability to store most of the input energy in the resonator, and little in the coupling network and surrounding ...

On the reciprocity factor for shielded microstrip

Microwave and Optical Technology Letters, 1995
AbstractNumerical results relating off‐diagonal elements of the impedance matrix [Z] for a two‐port waveguide junction are derived based on a general waveguide circuit theory [1] and a rigorous space‐domain approach. The junction between a coaxial line and a lossy shielded microstrip line is considered.

Q-factor of shielded inhomogeneously filled resonators

Radiophysics and Quantum Electronics, 1990
Factors which affect the intrinsic Q of shielded inhomogeneously filled resonators are analyzed. The dominant factor proves to be the resonator oscillation mode. Dielectric modes are characterized by high ohmic and low dielectric quality factors. For screened type modes the opposite is true.

Neutron self-shielding factors for simple geometrics

The International Journal of Applied Radiation and Isotopes, 1982
Neutron self-shielding factors are presented for slabs, spheres and cylinders irradiated in both isotropic and beam neutron fields. Macroscopic cross sections are tabulated for a number of dosimetry materials for thermal neutrons of 2200 m/s velocity.
