WIPL-D: Advances in EM simulation

Standard WIPL-D Pro 3D EM solver is based on higher order Method of Moment (MoM) solution of Surface Integral Equations (SIEs). Using patches of maximum size of 2λ the number of unknowns needed per λ
²
of the boundary surface area is reduced down to 25 (50) for metallic (dielectric structures). Owing to parallelization and usage of GPU cards the maximum solvable problem in one day is limited to a boundary surface area of 20,000 λ
²
. Using up to 3 symmetry planes and “smart reduction” option for expansion orders, the limit for a boundary surface area in λ
²
can be increased for an order of magnitude. Limits of standard WIPL-D Pro 3D EM solver are extended using 1) advanced matrix equilibration to balance source/field quantities in SIEs and basis/test functions in MoM solution, 2) new generation of integral methods for highly accurate evaluation of MoM matrix elements, 3) inclusion of frequency dependent material properties into simulation, and 4) modified Physical optics driven MoM.
