Charts for estimating the axial shielding factors of open-ended cylindrical shields
IEEE Transactions on Magnetics, 1999Axial 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, 1969The 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, 1995AbstractNumerical 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, 1990Factors 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, 1982Neutron 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.

Dipole Shielding Factor in Hartree–Fock Theory
The Journal of Chemical Physics, 1968In the coupled Hartree–Fock approximation, the dipole shielding factor is proved to be identically N / Z for any atomic S state. This suggests that variational-perturbation methods which yield poor values of the shielding factor may give unreliable Hartree–Fock values for other atomic properties such as the polarizability.
