Modeling and Simulation of Radiated Susceptibility (Immunity) of Electronics Products

Radiated susceptibility, or immunity, is an important part of Electromagnetic Compatibility (EMC) and evaluates the ability of an electronics device to operate normally when exposed to an externally generated electromagnetic field. Physical testing is typically used to check radiated immunity performance of electronic devices and various international standards, as well as to provide guidance on test setups and procedures.

Physical testing requires product hardware to be fabricated and as a result, is often performed very late in the design process.  Discovering susceptibility issues late in product development can lead to significant design modifications and delays in product entry into the market, with the associated costs and lost opportunities. Therefore, there is strong motivation to consider susceptibility performance early on and throughout product design and, for this, electromagnetic simulation is of great value.

Simulation can be used to:

• Compare different design options and optimize immunity performance
• Create a virtual twin of the EMC test environment
• Evaluate product performance under test conditions
• Help minimize physical testing
• Use a reverberation chamber to subject a product to fields incident from many different directions and with different polarizations

In this replay, we present a new electromagnetic simulation workflow for virtual reverberation chamber testing, using CST Studio Suite. Watch now to learn more!
