On the Shielding Effectiveness of Enclosures
IEEE Transactions on Electromagnetic Compatibility, 2005This paper deals with new definitions of shielding effectiveness, in particular for high-frequency and transient electromagnetic fields. They are practicable and supposed to better characterize the shielding ability than the commonly used definitions.

Shielding effectiveness measurements for ferromagnetic shields
2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007This paper proposes a new way to measure the shielding effectiveness of ferromagnetic shields. The procedure combines an experimental characterization of the shielding material to a forthcoming numeric simulation. Magnetic hysteresis is reduced to a series of equivalent B-H linear relations through an optimization procedure applied to a measured set of

Shielding Effectiveness Measurements for Ferromagnetic Shields
IEEE Transactions on Instrumentation and Measurement, 2009This paper proposes a new way to measure the shielding effectiveness of ferromagnetic shields. The procedure combines an experimental characterization of the shielding material and numerical simulations. In a first case, magnetic hysteresis is reduced to a series of equivalent B -H linear relations through an optimization procedure that is applied to a

On the shielding effectiveness calculation
Computing, 2013Numerical analysis of the effectiveness of electromagnetic shielding is performed. Its first objective is to propose a new approach to the shielding effectiveness theory based on a high-frequency numerical model that uses integral characteristics in contrast with the standard model.

On the effectiveness of the metamorphic shield
Proceedings of the Fourth European Conference on Software Architecture: Companion Volume, 2010In this paper we determine analytically the effectiveness of dynamic artificial diversity, i.e., artificial diversity in which the subject of the diversity is re-randomized periodically and mechanically. We refer to a mechanism that implements dynamic diversity as a Metamorphic Shield since this mechanism applies metamorphosis to the system's attack ...

Shielding effect of superconducting magnetically shielded room
IEEE Transactions on Magnetics, 1997A Superconducting Magnetically Shielded Room (SMSR) has been developed. Superconducting panels are soldered to form a shielding wall of which the soldered connections have normal conduction. Therefore, the Shielding Factor (SF) of the SMSR degrades especially at low frequency, which is different from a superconducting shielded room without a normal ...

Shielding effectiveness: A weighted figure of merit for space radiation shielding
Applied Radiation and Isotopes, 2020The risk to space crew health and safety posed by exposure to space radiation is regarded as a significant obstacle to future human exploration missions to the Moon, Mars, and beyond. Engineers developing future spacecraft or planetary surface habitats can benefit from detailed knowledge of a broad range of possible materials that could provide ...
