Researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland have combined antennas and solar cells in a breakthrough step towards the development of smaller and more lightweight satellites and autonomous antenna systems. Traditionally, telecommunication antennas and solar cells have been built separately to avoid interference, the researchers said. This … [Read more...]
New Tool Detects and Traces Electromagnetic Attacks
With the ability to interfere with or damage electronic devices, electromagnetic pulses (EMP) are considered one of the most dangerous threats facing modern electronic systems and infrastructure. Man-made EMPs in particular can be used to deliberately disable power grids and defense and security systems without leaving any indication as to the specific nature or origin of the … [Read more...]
Analysis on Shielding Effectiveness of Board Level Shielding with Apertures
Brian She Laird Technologies ABSTRACT There is a growing need to evaluate the shielding effectiveness (SE) of board level shielding (BLS). By means of a reverberation chamber, we performed a series of shielding effectiveness test for board level shielding products with different apertures. In addition, an analytical SE formulation has been developed in comparison with … [Read more...]
The First Practical Approach to EMC for Functional Safety (EMC Risk Management)
Keith Armstrong Cherry Clough Consultants Ltd. There are now many standards on Functional Safety (Risk Management) that apply to relevant electronics, including IEC 61508 [1] and the standards developed from it listed in Section II of [2], and ISO 14971 [3]. They all require that EMI be dealt with, but complying with emissions and immunity EMC test standards, even using … [Read more...]
