Описание: | Field, circuit, and cable solvers are interfaced at cable terminations and along the cable shields, which results in a coupled system of equations that is solved simultaneously at each time step. To efficiently simulate such complex structures, three different solvers are hybridized: The accuracy, efficiency, and versatility of the hybrid simulator are demonstrated by analyzing several EMC/EMI problems. Computation of the external and guided fields is accelerated using FFT-based algorithms and parallelization. A fast and rigorous hybrid time-domain simulator for analyzing wave interactions with complex structures involving electrically large platforms along with cable-interconnected antennas, shielding enclosures, and printed circuit boards is described. The resulting solver permits the analysis of electrically large and geometrically intricate structures loaded with cables. A TDIE-based field solver for computing external fields on platforms, antennas, enclosures, boards, and cable shields; a MNA-based circuit solver for computing currents and voltages on circuits; and a TDIE-based cable solver for computing guided fields along cables. |
