Thermal radiation

Thermal radiation is the transmission of heat by electromagnetic waves emitted by a physical body. A typical heat radiation via electromagnetic waves is infrared radiation.

Electromagnetic waves are generated by the coupling of electric and magnetic fields. Electrical devices and lines carry low-frequency magnetic fields. Cell phones or WLAN, on the other hand, carry high-frequency electromagnetic fields. Electromagnetic waves play a not inconsiderable role in product development. On the one hand, one wants to optimize the function of products. On the other hand, radiation exposure and heat generation must be kept as low as possible. Engineering simulation calculations also play an important role in this environment.
