Ferrite Devices

This course covers the basic principles of ferrite devices, with a special emphasis on microwave propagation in ferrites and the Faraday rotation concept. For instance, learners will explore how the Faraday rotation effect is utilized in the creation of devices such as isolators and circulators, which exhibit non-reciprocal transmission characteristics. The course also delves into the properties of ferrite materials, including their magnetic properties and preparation methods. Additionally, it discusses the permeability of ferrites and wave propagation in the bias direction, leading to Faraday rotation. The course concludes with an in-depth explanation of how isolators and circulators operate based on Faraday rotation.
