Apsim FDTD

To discover early in the design and development, understanding and correcting of electromagnetic radiation is very important. The traditional electromagnetic simulation tools are static or similar static TEM analysis. However, the frequency becomes higher , TEM method can not accurately calculate parasitic electromagnetic field propagation ( such as secondary field , three games , etc.) , but these parasitic field just seriously affect circuit delay , crosstalk . Because the operating frequency increases , the attendant problems are likely to have a greater radiation noise. Tiny feedback current tends to produce a lot of radiation impact . If you do not first obtain a band for your interest in accurate electromagnetic analysis program , those EMI and electromagnetic radiation can not be critical to early detection and exclusion .
