International Intellectual Group, Inc.
A world leader in modeling of the diffraction gratings efficiency for spectroscopy, astronomy, telecommunications, photolithography, and nanotechnology.
Our company has a wealth of experience in diffraction efficiency modeling of various types of relief and phase gratings. The most important outcome of our 30 years’ work was the advent of PCGrate®, a modeling tool for analysis and optimization of the absolute diffraction gratings efficiency by an accurate boundary integral equation method. The development of such sophisticated software became possible as a result of the multidisciplinary collaboration between many experts in the domains of theoretical physics, applied mathematics, and computer science.
