Dr Simone Zonetti, Applications Engineer, COMSOL
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 will discuss the simulation of electromagnetic coupling in a variety of different applications, considering examples of capacitive, inductive and radiative couplings in frequencies from the kHz to GHz range. We will 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 will illustrate how to simulate antenna crosstalk using COMSOL Multiphysics®. We will conclude this webinar with a Q&A session.
