Abstract :
A novel method is proposed to take into account radiation effects due to the open boundary of a PCB on ground bounce between isolated power/ground planes by the 2D-FDTD method hybridized with an integral equation formulation for the exterior field. An efficient simulation procedure is established by casting equivalent inductances and capacitances with phase retardation into 2D-FDTD. Simulation results for the radiation effects due to the open boundary or among isolated power/ground planes are presented and validated by measured data.
