The use of genetic algorithms in electromagnetic simulation techniques can be instrumental in finding the optimal location to place an antenna or to maximize signal strength. Remcom has several materials that demonstrate the implementation of a genetic algorithm using XFdtd.

With Remcom's new generation of XStream, now included at no cost in XFdtd, the power of GPU acceleration allows genetic algorithms to calculate extremely fast. This makes the use of genetic algorithms a reality for anyone using XFdtd for their EM simulations.

Technical Paper: Determining an Optimal Antenna Placement using a Genetic Algorithm
Determining the optimal location for an antenna on a platform is limited by the humans involved. Best guesses are based on previous experience and rules of thumb. As platforms become more complicated, determining the placement for antennas becomes an increasing challenge. This paper demonstrates XFdtd's effective implementation of a genetic algorithm to determine the optimal placement of an antenna on a platform.

PowerPoint Presentation: Using a Genetic Algorithm for Antenna Placement
This case study shows the use of a genetic algorithm to add a second antenna to a military Humvee in order to maximize electric field strength in front of the vehicle. For this analysis, the new antenna is modeled as a basic monopole consisting of a feed and a wire. Antenna structure, allowable regions, evaluation process, iterations, optimal location results, field strength comparison, and verifications and conclusions are demonstrated.

Video: Using a Genetic Algorithm to Optimally Place an Antenna With XF7
A variation of the PowerPoint presentation above, this video describes the process by which a genetic algorithm was used in XFdtd Release 7.0 to optimize the placement of a signal-jamming antenna on a military Humvee. The goal of the optimization was to find the location on the Humvee that resulted in the highest amount of power on target at a position several meters in front of the vehicle.
