Is Electric Equipment Grounding the Basic Protection Means Against HEMP?
Abstract The article discusses the differences between the electromagnetic pulses at lightning (LEMP) and at high altitude nuclear explosion (NEMP or HEMP). The article also shows that these differences do not allow to transfer LEMP experience on to NEMP. The author questions the effectiveness of grounding of electronic equipment as the main protection principle against … [Read more...]

Review of MIL-STD-461 CS103 Intermodulation, CS104 Rejection of Undesired Signals and CS105 Cross-Modulation
Introduction Rapid technology advances in the wireless communications world make test and evaluation of Radio Frequency (RF) devices a difficult subject. It seems that by the time a new device hits the market, it has been made obsolete by the next generation. I recall hearing from a major electronics manufacturer CEO that 90% of sales happen within 90-days of market release … [Read more...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
