The physics of electromagnetic coupling through space is fundamental to modern technology. It is exploited in some devices such as RFID tags and directional couplers to communicate information. In other devices, electromagnetic interference (EMI) is an unwanted effect that must be controlled: for example, the problem of crosstalk in electrical circuits and cables.
In this webinar we discuss the simulation of electromagnetic coupling in a variety of different applications, considering examples of capacitive, inductive and radiative couplings in frequencies at the kHz to GHz range. We show how modelling can provide insight into design, either to improve the quality of a communication device, or to mitigate EMI through effective electromagnetic shielding. A live demo illustrates how to simulate antenna crosstalk using COMSOL Multiphysics®.
We conclude this webinar with a Q&A session.
