This application presents capabilities of WIPL-D software suite for full wave electromagnetic simulation of waveguide divider realized in substrate integrated waveguide technology, along with simulation results and requirements. WIPL-D is modern and extremely efficient Method of Moments full wave 3D EM simulator.
The divider in wave guide technology is moderate size model with certain smaller details, so WIPL-D advantages are pronounced in full extent. The simulation model has low number of mesh elements and low number of unknown coefficients needed to determine current distributions. The code executes rather quickly on inexpensive CPU platforms thanks to excellent parallelization capabilities. The simulation model of the waveguide divider originates from the provided CAD file, imported into WIPL-D Pro CAD. The model is symmetrical so only quarter of the model is simulated. This dramatically saves resources and simulation time. The device is designed for 60 GHz.
The simulation is carried out by using only CPU technology considering the fact that the model is not electrically large. The simulation requires only 8,100 unknown coefficients in MoM matrix, but it is carried out 4 times to generate results for all 5 ports (model symmetry). The total simulation time per frequency point is 39 sec on multicore desktop PC:
