The new 3D EM solver EMPIRE XCcel 5.3 will be presented at IMS booth 2236. EMPIRE XCcel covers nearly all today’s design challenges for RF designers, like antennas, passive circuits, packages, waveguides or EMC/EMI problems. Due to the unique structure and processor adapted code generation a simulation performance up to 1600 million FDTD cells per second can be achieved on a conventional PC with full access to the built-in memory. Thus very complex structures can be modeled very fast and highly accurate (e.g. 23 lambda 16 lambda 4.5 lambda array antenna simulation at 24 GHz needs only 12 GB memory).
