[[EM.Picasso]] (Printed Circuit and Antenna System Simulator and Optimizer) is a simulation software tool for analysis and design of planar microwave circuits and antennas. It features a computationally efficient simulation engine that is based on the 2.5D Method of Moments (MoM). The method of moments is a full-wave integral-equation-based numerical technique for solving Maxwell’s equations. Rather than discretizing the entire computational domain, MoM takes advantage of the analytical solutions that might be available for the background structure to reduce the mesh size significantly. This is embodied in the form of dyadic Green’s functions, which are indeed the solutions to the background boundary value problem with elementary sources. MoM’s highly reduced mesh size can lead to faster computation times and lesser memory requirements. This is particularly important for antennas and other open-boundary structures. In such cases, the appropriate Green’s functions take care of the unbounded background medium of the problem, which inherently has infinite extents.
