Presentation: High-Fidelity RCS Simulation of a Turbine Blade
10/24/2013
Radar scattering from a turbine’s moving blades can interfere with Doppler radar systems, producing ghost images. Understanding the scattering properties of a blade can provide radar manufacturers with the necessary information to mitigate any potential issues.

Vehicle-To-Vehicle Communication Using MPI + GPU Technology
6/24/2013
Inter-vehicle communication (IVC) systems promise many potentially beneficial services. This example considers an IVC system functioning in highway traffic conditions on a dry road surface. XFdtd EM Simulation Software provides an accurate and efficient evaluation of actual operating scenarios prior to fabrication.

Analysis Of Wi-Fi Propagation in Aircraft Interior Using MPI + GPU Technology
5/17/2013
In-flight Wi-Fi access is being introduced to many commercials flights; however, due to the complex cabin environment with varying passenger sizes and seating layouts, it's possible for poor signal reception to occur. Recently a study was performed experimentally where sacks of potatoes were used to simulate passengers in an aircraft in an attempt to eliminate low-signal areas. Simulating such problems was virtually impossible in the past due to the large size of the aircraft cabin and the high frequencies involved. With XFdtd, these simulations are possible due to the large memory and MPI + GPU processing features.

Remcom Case Study: MRI Coil Improvement For Cardiac Imaging In Mice
2/11/2011
It is common knowledge that mice often serve as models for the study of human health conditions and experiments to improve human medical treatments. But most people probably don’t consider the accuracy of the experiments themselves, focusing instead on the results to give us confidence in the progression of our health care.

Modeling The Effects Of Wind Turbines On Radar Returns - White Paper
12/6/2010
Wind turbines located near radar installations can significantly interfere with a radar’s ability to detect its intended targets. In order to better understand and mitigate the adverse effects of wind turbines on radar, the government and wind farm community need tools that can be used to analyze the radar returns from wind turbines. Remcom’s XGtd® software is a high frequency solver capable of calculating the radar cross section of electrically large objects. In this paper, interference from wind turbines is predicted using XGtd simulations and new post-processing algorithms that calculate Doppler shift quantities based on points of interaction with the rotating turbine blades. Results of the analysis are used to calculate the bistatic radar cross section and Doppler shift from two blade orientations. In addition, the time-varying monostatic radar cross section and Doppler shift for a single wind turbine are analyzed and shown to agree well with measured data from actual wind turbines. By R.
