Electromagnetic Interference Fundamentals (Webinar)

In Electromagnetic Interference Fundamentals, you'll learn ...

• The definition of Electromagnetic Interference (EMI) and the way it is produced and characterized
• The electromagnetic spectrum from low to high frequences
• Specific EMI threats and methods to protect against them

Overview

---

In this webinar, Electromagnetic Interference (EMI) is defined and Electromagnetic Field Theory is described as the fundamental principle that explains the manner in which EMI is produced and characterized. General characteristics of electromagnetic radiation are provided with a review of the electromagnetic spectrum from low to high frequencies prior to typical EMI examples.

EMI examples are provided to establish distinction between naturally-occurring and man-made sources. EMI phenomena is described to establish the distinction between radiative, conducted and coupled mechanisms. Specific EMI threats are described to introduce the manner in which these threats can be prevented and/or minimized by the use of band-reject filters, shielded and twisted cables, waveguides, fiber-optic cables, high power transmitters locations and use of Faraday cages. A specific treatment of EMI threats to medical devices and testing is also described.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify examples of electromagnetic radiation.
• Describe naturally occuring EMI threats.
• Explain man-made EMI threats.
• Assess preventative measures to protect against specific EMI threats.
