A CAD TOOL UTILIZING FAST HYBRID MM/FE/MoM/FD TECHNIQUES

摘要

To meet the rapidly increasing demand for advanced microwave components and antennas in wireless terrestrial and satellite-based communications, accurate and efficient CAD tools are critical. Due to efforts made during the 1990s ― the decade of global 3D electromagnetic (EM) field solvers ― the task of accurate analysis of components can be considered as being largely solved. Therefore, current challenges for CAD software relate to a new quality of efficiency and speed. Communication industries demand a drastic reduction in time-to-market, where only highly optimized microwave components/systems will meet the tight requirements of current and next generation applications. In this context, fast EM-based CAD tools are desired, yielding accurate, optimized designs within extremely short response times. To achieve this requires flexible hybrid solutions, which typically can go beyond the possibilities of single global 3D solvers.
