INTRODUCTION Selecting an antenna for testing can sometimes be straightforward but often requires some specific consideration. One aspect in antenna selection is knowing the intended test frequencies and then selecting a matching antenna. Not all antennas are created equal, and when it comes to frequency different antenna styles perform better at some frequencies and … [Read more...]

Why ANSI/ESD S20.20 1-Foot Rule for Charge Generators needs to be Increased to 1-Meter for Aerospace & Defense
INTRODUCTION IN THE SEMICONDUCTOR SECTOR TODAY, ESD sensitive devices can be damaged at <+/-50 volts. Aerospace & Defense cannot issue a Return Materials Authorization (RMA) for an ESD sensitive device that fails in space or a nonfunctioning weapon system in-theatre. The fact that extruded film can charge up to over +/- 100,000 volts below 20% RHhas been … [Read more...]

French Security Firm: Hackers use Radio Waves to Hijack Smartphones
Security researchers have reportedly discovered that hackers can use radio waves to hijack data on Android smartphones and iPhones through Google Now and Siri. Hackers accomplish this by sending radio waves to the devices and tricking users into sending them information by responding to voice commands. “According to French security firm ANSSI, which made the discovery, the … [Read more...]
‘Electrosmog’ to Help Power Devices in UK
Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
A Solution to Enhance Reproducibility With Radiated RF Emission and Immunity Measurements?
Mart Coenen EMCMCC, Breda, the Netherlands. Most, if not all electrical and electronic appliances have to be tested on their radiated RF emission and their immunity against RF radiated fields. This radiated testing occurs either on an open area test site (OATS) or in an anechoic or semi-anechoic room (SAR). The electrical and electronic appliance to be measured … [Read more...]
Outdated 2G Mobile Phones Could be Used to Hack Computers
A team of computer security experts from Ben-Gurion University in Israel have discovered 2G mobile phones could hack air-gapped computers and steal data via radio frequency wireless electromagnetic waves and a GSM network. In order for this process to work properly, both the 2G phone and the targeted computer must have malware installed on them. “Computers naturally emit … [Read more...]
