Optimized Antenna Design Using GPU Acceleration and Particle Swarm Optimization

Devices designed for free space operation often fail to meet expectations when deployed in their actual environment. This study considers the example of designing a broadband antenna for an unattended ground sensor using Remcom's XFdtd Release 7 (XF7). To address the challenge of attaining acceptable performance over both dry and wet ground conditions, we use Particle Swarm Optimization (PSO). XStream GPU Acceleration and MPI + GPU technology make this type of sophisticated simulation strategy possible, completing multiple optimizations with hundreds of generations to converge on the best values.

High Fidelity Modeling of Spatio-Temporally Dense Multi-Radio Scenarios

Heterogeneous, mobile wireless networks are becoming increasingly difficult to validate for operational use, depending on digital simulation of the wireless channels to properly predict behaviors in the field. The complexity of these simulation scenarios demands high fidelity modeling of the physical channels at very dense resolution of the trajectories of each moving radio in order to handle rapid changes and multi-path, a high performance computing problem of its own. Presented is an approach to reduce the run-time of these high fidelity simulations by constructing precise results based on adjacent ray-paths from a lower resolution simulation. Speed and accuracy trade-offs are presented for this approach in typical urban scenarios, demonstrating its effectiveness in meeting the growing needs of wireless channel emulation.

Complex 3D Modeling of Sea to Land Scenario

This paper presents results from sea to land propagation using Wireless InSite. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.

Using Simulation to Optimize Safety, Performance, and Cost Savings When Integrating an Antenna Onto a Platform 

Successful integration of an antenna onto a vehicle platform poses many challenges, from vehicle features and motion impacting antenna performance to environmental factors such as terrain and buildings reducing system effectiveness. Furthermore, radiation hazards may pose risks to nearby personnel. This paper provides a variety of examples of how modeling and simulation can be used to analyze antenna performance, identify problems, and evaluate potential solutions.
