Research on the Shielding Performance of Electromagnetic Shielding Clothes
Advanced Materials Research, 2010Electromagnetic shielding clothes for protecting human exposure from harmful radio waves have been commercialized. However, most research has so far focused on the fabrics. In this paper, based on the orthogonal experiment method, design the structure of the electromagnetic shielding clothes, and conduct the performance test.

Recyclable Materials as a Means of Electromagnetic Shielding
2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2018Currently, shielding effectiveness represents a fundamental property of materials designed to resist electromagnetic fields effect. There are many materials suitable for shielding; however, the authors decided to use recyclable plastic materials whose surface was provided with gold or carbon nano-layer. The experiment aimed at determining the influence

Polypyrrole-coated Nonwovens for Electromagnetic Shielding
Journal of Industrial Textiles, 2008Several shielding applications, to protect human health and electronic devices against dangerous effects of electromagnetic radiation, require solutions that fabrics can suitably fulfill. Here, we will discuss the electromagnetic interference shielding effectiveness of polypyrrole-coated polyester nonwoven textiles, in the frequency range 100—800 MHz ...

Applied Mechanics and Materials, 2013
A new kind of the electromagnetic shielding composite coatings with high performance was prepared using the Ni-Cu-coated glass fibers and nickel powders as fillers and using epoxy resin as binder. The effects of the fibers on the conductivity and electromagnetic shielding effectiveness of the coatings were studied. The study results show as follows: 1)

Measurement of the electromagnetic shielding capabilities of materials
Proceedings of the IEEE, 1986Electromagnetic shielding is typically measured in terms of insertion loss, that is, the reduction in the fields coupled between a transmitter and a receiver which results from interposing the shield material. Although the insertion loss concept is simply stated, questions arise when one attempts to interpret specific insertion loss measurements ...

Reciprocity in electromagnetic shielding
IEE Seminar on Shielding and Grounding, 2000Electromagnetic shielding is one of the most widely used techniques in design for EMC. It is extensively covered in the technical literature but is still widely misunderstood and the accepted calculation methods frequently misapplied. This paper attempts to throw some more light on the subject and demonstrate the relevance of the reciprocity theorem to

Electromagnetic shielding mats: facts and fiction
Radiation Protection Dosimetry, 2006The use of electricity is accompanied by electric and magnetic fields which, intended or not, became a part of our environment. However, fear from environmental electromagnetic fields (EMFs) is widespread and so is business with fear. A number of more or less serious products including miracle products are placed on the market partly at excessive costs.
