Atomic Susceptibilities and Shielding Factors

Physical Review, 1969
A calculation of electric and magnetic susceptibilities and shielding factors for closed-shell atomic systems based on relativistic Hartree-Fock-Slater (RHFS) electron theory is presented. Numerical results are given for the electric dipole and quadrupole, and for the magnetic dipole and octupole cases for closed-shell atoms and ions from $Z=2$ to $Z ...

Influencing factors and rules of shielding effectiveness of electromagnetic shielding clothing sleeve

International Journal of Clothing Science and Technology, 2020
PurposeThe change rules of the shielding effectiveness (SE) of the sleeve has not been clarified, which leads to the lack of the basis for the design, manufacture and evaluation of the electromagnetic shielding (EMS) clothing.Design/methodology/approachAccording to a simplified analysis model, a series of sleeve samples with different fabrics and ...

A new estimation of the axial shielding factors for multishell cylindrical shields

Journal of Applied Physics, 2000
A new, more accurate formula describing double and multiple-shell axial magnetic shielding is obtained as a result of numerical verification of existing estimations. A standard ANSYS® software package was used. Parameters of the numerical model are as follows. Two concentric, closed cylinders of equal thickness and constant permeability are considered.

Gamma shielding factor for typical houses in Brazil

Radiation Protection Dosimetry, 2006
The housing features in a country depend much on its climate. Dwellings in warm countries are much lighter constructions than in cold ones, which will reflect on the amount of shielding against radiation they provide. In addition to that, wealth is another factor that influences the building's finishing.

The shielding factor of underground cable sheaths

Proceedings of the IEE - Part II: Power Engineering, 1953
The shielding factor of a cable buried in the ground has been investigated, and it is shown that it may be considered in terms of three components. The first of these depends on the sheath construction only, and is the factor normally considered for high-frequency shielding.

Determination of the shielding factors for gamma-ray spectrometers

Applied Radiation and Isotopes, 2014
A method for determining the shielding factors for gamma-ray spectrometers is described. The shielding factors are expressed by decomposing the peaked background of the spectrometer into contributions of the detector, spectrometer shield and ambient radiation to the spectrometer background.

Impulse Wave Attenuation Factor of Shielding Cages

3rd Symposium and Technical Exhibition on Electromagnetic Compatibility, Rotterdam, 1979
The present work shows the attenuation factors of an imperfect Faraday cage with respect to stiff front time Impulse waves. The aim of this work is to simulate the comportment of sensitive measuring electronic devices boxes against inpulse phenomena. For testing the cage perfomances high precision data acquisition and processing is needed.

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.

Electronic Polarizabilities and Sternheimer Shielding Factors

Physical Review, 1963
A new method is developed for determining the distortions (polarizabilities) induced in electronic distributions by valence electrons and/or crystalline fields and their effect (expressed as Sternheimer shielding factors) on magnetic and electric hyperfine interactions.

Atomic polarizabilities and shielding factors

Advances in Physics, 1962
Abstract A detailed discussion is given of the methods of calculating atomic polarizabilities and shielding factors and the relationships between them are demonstrated. The formulation of the uncoupled Hartree-Fock approximation is presented and it is shown that the methods are all approximate versions of it.
