Supporting Future Aircraft Certifications with EM Simulations
Electromagnetic environments, such as high intensity radiated fields (HIRF) and lightning, can degenerate aircraft safe operation and even cause catastrophic effects if precautions aren't taken. The trend toward all-electric aircraft increases the number of aircraft functions performed by avionics. The risk of failure is even higher for modern aircraft with structures made of carbon-fiber composites (CFC).
Electromagnetic environmental effects (E3) can cause electronic devices to malfunction or fail altogether. High Intensity Radiated Fields (HIRF), from sources such as TV and radio stations, radar and satellite communication systems, may disturb the safe...
The Modeling of Lightning Strikes
This article examines the modeling of lightning strikes using CST MICROWAVE STUDIO® (CST MWS). The surface current distribution due to a double-exponential waveform lightning strike on the nose of an airplane is calculated by way of example.
Electrical Fast Transient/Burst (EFT/B) Susceptibility of an LV Circuit Breaker
The coupled voltage at component level has been simulated using CST MICROWAVE STUDIO SUITE® for two PCB releases of the same Low Voltage Circuit Breaker (LV-CB) electronic control scheme. The results show a good agreement with actual measurements.
Ku-Band Traveling Wave Tube
This article describes the hot and cold test analysis of a traveling wave tube. Such a simulation uses a broad spectrum of the solvers available in CST STUDIO SUITE®. The complete simulation procedure is shown. First the electron gun is analyzed. Then...
Bistatic Radar Cross Section: NASA Almond Benchmark
CST MICROWAVE STUDIO® (CST MWS) is used to compute the radar cross-section (RCS) of the NASA Almond benchmark. The Time-Domain solver in CST MWS can deliver the RCS results at arbitrary frequencies defined by the user which is a tremendous advantage for...
