IMST announced it will present the new 3D EM solver EMPIRE XCcel 5.3 in 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 x 16 lambda x 4.5 lambda array antenna simulation at 24 GHz needs only 12 GB memory).
