Fast 3D planar electromagnetic analysis via Unified-FFT method

Microwave and mm-wave circuits today are larger, faster, and more integrated than ever. This trend continually increases the requirements and applications of electromagnetic simulation. To satisfy this demand, a Unified-FFT method is developed, implemented, and tested, with promising results. The Unified-FFT method combines the fast Matrix Solve Operations (MSO) of the FFT-enhanced Pre-Corrected FFT (PFFT) method with the fast Matrix Fill Operations (MFO) of the FFT-enhanced Sonnet V13. Together, these operations allow for high-accuracy simulation with reduced size constraints, and overall speed improved by more than an order of magnitude.
