Electromagnetic Screening

The paradoxical augmentation of the electromagnetic response of an inner core by a conducting cover is reexamined by investigating the behavior of a cylindrical model to establish the geometrical independence of the negative screening phenomenon. The theory is developed for the coaxial cylindrical system in analogy with the spherical case. Results of numerical evaluation of the analytical expressions for the screening factor prove the geometrical independence of the phenomenon of negative screening, as indicated in earlier studies.

Electromagnetic Screening

Metal foams are very interesting materials in new emerging technologies as aeronautic, spatial research, auto-motion or heat exchanger, but there are other areas in which these materials could be advantageous. Here is a new proposal for using these materials in electromagnetic shielding. The goal is to demonstrate that, although having a smaller effective electrical conductivity than massive materials, it is possible to attain operative electromagnetic shielding with a reduction of mass and, in addition, to bring together in a single product a supplementary protection against vibrations, impact, noise, etc., as corresponds to the well-known properties of porous materials. In terms of the operating frequency, conductivity and thickness of the metallic foams the electromagnetic screening was calculated. It is shown how to guarantee a specified shielding the necessary thickness in porous materials with respect to massive metals obeys to a quadratic relation.
