EM simulation can also help device manufacturers by showing that their devices fall within the regulatory standards set for non-ionizing radiation. While scientific studies over the past thirty years have not shown harmful effects of exposure to low-level EM radiation sources, they have also not conclusively ruled out the possibility.ĮM simulations can aid this research by modeling the effects of EM radiation on human tissue without exposing any human beings to actual risk. The effects on the human body of non-ionizing sources of radiation-such as what are found in electronic devices-are currently under study.

These come from ionizing sources of radiation, such as X-rays or gamma rays. High levels of electromagnetic radiation manifest themselves quickly in the forms of burns or rashes. Simulate electromagnetic interference on other electronic components and nearby devices. However, EM simulation can help engineers overcome this challenges by modeling which placement of antennae and compact isolation features within the device leads to the best performance. Having so many components in such close proximity to each other all trying to send and receive signals causes many issues, with stronger signals drowning out weaker ones-much like too many speakers in a small room talking over each other. These include antennae for WiFi, Bluetooth, GPS, and as many as four for LG cellular connectivity-and that’s just what’s in a smartphone. The typical smartphone, for instance, doesn’t just have one antenna-it can have over half a dozen. Improve antennae efficiency to reduce coupling issues.Īlthough the average consumer doesn’t think about it much, antennae have become ubiquitous components among modern connected devices. It can then help engineers understand how to use these efficiencies in their designs to provide greater capacity to end users. This is because, as devices provide more processing power and increased storage, the demands placed on them increase.ĮM simulation can drive improvements by showing how reduced chip sizes have increased speeds and power density. Despite the improvements made year after year in this area, the demand for faster, more powerful devices with longer battery lives has yet to slow down.

One of the most obvious applications for EM simulation is in the design of new electronic components for data processing and storage.
