Electromagnetic Modeling Consultancy

3D Electromagnetic modeling has in recent years become a powerful tool to get insight into electromagnetic and EMC problems. Todays computational power together with the ability to develop 3D computer models allow electromagnetic phenomena to be understood via computer simulations.

After a 3D model is created ports or fields are defined that excite the model. The Electric and Magnetic field response to this excitation is calculated. The result can be a plot showing the E and H fields, a radiation plot or a s-parameter dataset describing the linear behavior of the model at the ports.

Models can be imported from cad data or created from scratch. They can be changed by visual basic scripts, this adds a powerful possibility to control the model by programming. This flexibility to change the model allows a design by simulation approach. To see a programming example, look to my model of a power transistor.
