Measurement Uncertainties in Outdoor Far-Field Antenna Ranges

Consolidated methodologies have long been established to assess measurement uncertainties in both near-field and compact-range antenna measurements. However, there is currently no analogous methodology for outdoor far-field measurement facilities. This article presents a framework for assessing the measurement uncertainties on an outdoor far‑field elevated range.

NASA Space Shuttle’s Return to Flight: The Untold Electromagnetic Backstory

The 2003 Columbia re-entry accident was caused by a piece of liberated external tank foam that struck and damaged the left leading edge during powered ascent. Computational and experimental electromagnetics were ultimately applied to foster the development of a new NASA Ascent Debris Radar (NDR) for the remaining 22 Shuttle missions. In the process, countless static and dynamic radar signature and EMI/EMC calculations and tests were completed to assure this safety-critical radar system was ready for the return to flight (RTF) missions.

Capacitors: Theory and Application

This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.

Ohm’s Law Also Applies to ESD‑Induced Heat Pulses

Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.
