Since 2000, Golden Engineering has been working in the field of electromagnetic simulation from very low to very high frequencies, including the modeling of electric circuits, transmission lines, wave guides, and antennas. The need of having available an integrated simulation tool for solving problems in an extremelly wide frequency range, has led us to the development of a general full-wave calculation technique based on the Method of Moments for 3D structures.Golden Engineering has then created AN-SOF, an innovative software for the modeling of 3D arbitrarily shaped wire structures and the computation of their electromagnetic responses, including currents and voltages in passive circuits as well as dynamic electromagnetic fields in radiation and scattering problems.Several features of AN-SOF have been added and improved with time, such as conformal geometry, 3D graphical user interfaces and CAD (Computer Aided Design) tools for the input data, while xy-charts, polar plots, 3D radiaton patterns, and Smith charts for the output data.These all-integrated graphical tools have converted AN-SOF into a comprehensive program system for the analysis and design of microwave, wireless, and telecommunication devices.
