Application Examples of Electromagnetic Wave Simulation Software “Poynting”in Manufacturing Industry

It is becoming hard to produce designs when developing electronic equipment because of advances in packaging technology and strict regulations. It is specifically difficult to conform to electromagnetic compatibility (EMC) standards in the design phase. And this is a factor that causes development costs to increase. By implementing a simulation for virtual evaluation in the design phase of a printed circuit board (PCB), it becomes possible to significantly reduce the cost of measurement and evaluation. EMC measures in the design phase can be implemented by performing electromagnetic wave analysis of the whole model of a product comprised of a PCB, wiring and housing. To meet this need, Fujitsu has developed the electromagnetic wave simulation software “Poynting,” that it markets and supports. Poynting is capable of rapidly carrying out calculations in a large-scale model with a high-performance computer system. It is suitable for analyzing noise in electronic equipment. This paper describes the features and advantages of Poynting. It also describes application examples of carrying out electromagnetic interference (EMI) analysis on power electronics equipment, near-field electromagnetic analysis of a PCB and electrostatic discharge (ESD) analysis of a cellular phone.
