EM simulation on a 5.6GHz Antenna Array (Source: Flomerics)

Flomerics has introduced version 7.5 of its MicroStripes 3D EM simulation solution for RF/microwave and antenna design which integrates with Applied Wave Research's Microwave Office circuit design software. The new version enables users to import any desired excitation waveform during the modeling process, run the simulation, and evaluate the results without any additional post-processing. This makes it possible, for example, to simulate the effect of a lightning strike, electromagnetic pulse (EMP) or electrostatic discharge (ESD) on a system using a pre-computed, analytic or measured waveform. In version 7.5, ground planes can also be used for models without meshing all of the space between the system and ground plane.

A specific algorithm accounts for the effects of the ground plane outside of the simulation domain, substantially reducing solution time. MicroStripes 7.5 reduces the computational resources required to model ferrite tiles by providing its unique SmartPart compact model methodology of ferrite tile absorber which incorporates the effects of the tiles into the simulation without having to include them in the mesh. In a recent benchmark of an anechoic chamber performed by Siepel, the ferrite tile SmartPart reduced solution time by a factor of 15 without sacrificing accuracy.
