Principles of Prediction builds electromagnetic simulation software and optimization algorithms for designing wireless hardware. Its Virtual Laboratory suite characterizes design problems using the calculus of variations and moment-based techniques, so design parameters are optimized simultaneously with the solution of Maxwell's equations rather than through repeated iterative redesign. The algorithms are inherently parallel and run on modern massively parallel computing architectures. The company applies the suite to low-latency wireless links for high-frequency trading, including multi-band waveguide-fed dish antennas with dual reflectors, corrugation, and phase encoding.
