U.K. National Weather Service Protests Wind Farm Construction, Citing Radar Interference
The Met Office, the U.K.’s national weather service, is protesting the construction of a wind turbine farm near one of its weather stations in Llanllwni, Carmarthenshire, Wales, claiming that interference is caused by the structures reflecting electromagnetic waves emitted by radar. According to the Met Office, the reflected electromagnetic waves can create “clutter” that … [Read more...]
On Mismatch Error Estimation by Measurement of Radiated Disturbances
Jan Sroka Warsaw University of Technology Original article translated from Polish. Introduction The quantity of interest (measurand) by the measurement of radiated disturbances is either electric or magnetic field strength. It is detected with an antenna and converted to the signal in the 50Ω coaxial system. This signal is transmitted to the measurement receiver via coaxial … [Read more...]
Ministry of Defense Launches Anti-Jamming Military Satellite
The Ministry of Defense and aerospace subsidiary Astrium have launched a military satellite equipped with “anti-jamming” capabilities into orbit. The British-made Skynet 5D communications satellite was created to “bolster and extend the UK’s military telecommunications system.” “The launch of Skynet 5D marks another milestone in this very successful program,” Defense Secretary … [Read more...]
Editorial: A Year for Europe
Welcome to the third annual issue of Interference Technology’s Europe EMC Guide. 2013 has been designated the European Year of Citizens to commemorate the 20th anniversary of EU citizenship under the Maastricht Treaty. The European Year is both an interdepartmental and grass-roots-level campaign that aims to raise European awareness of citizen rights. Therefore, Interference … [Read more...]
Investigation of Vehicle Radiated Emissions Measurement Practices
Alastair R. Ruddle, Ph.D. Computational Electromagnetic Specialist, MIRA Limited Radiated electromagnetic emissions measurement standards for road vehicles were developed at a time when the main threat posed by radio-frequency noise from vehicles was interference to broadcast transmissions from spark ignition systems. Since that time, however, on-going technological … [Read more...]
Potential Impacts of Electromagnetic Weapons on the Critical Infrastructures (View from 2012)
William A. Radasky IEEE Life Fellow WHAT IS IEMI? In recent years, Hollywood has indicated that criminals and terrorists could use electromagnetic (EM) weapons to black out a portion of Las Vegas (Ocean’s 11) or take down a counter-terrorism computer center (24). Is this fact or fiction? It turns out that Hollywood in this case is leading the public and police agencies in … [Read more...]
Antenna Coupling Inside an Aircraft Using ACA Direct Method
Pascal De Resseguier, Entares Engineering, Toulouse, France Yannick Poiré and Samuel Leman, Nexio, Toulouse, France ABSTRACT A proper study of electromagnetic interferences inside an aircraft has become essential with the recent increase of electronic devices on board. Their effects on the airplane communication and electronic systems need to be considered at an early stage … [Read more...]
Measurement Analysis of Pulsed Disturbance Immunity
Lars Glaser Summary Physical problems when analyzing an electronic system's interference immunity. Introduction Today it is becoming increasingly difficult to locate faults in state-of-the-art electronic circuits. Apart from a greater complexity (and consequently a much higher number of potential fault sources), small mechanical dimensions make it more and more difficult … [Read more...]
