3. 2. Magnetically tunable microwave resonator/filter

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zhi Ye; [2022]
   Nyckelord :Magnetic tuning; Ferrite; Substrate integrated waveguide resonator; Substrate integrated waveguide filter; Magnetisk inställning; Ferrit; Substratintegrerad vågledarresonator; Substratintegrerad vågledarfilter;

   Sammanfattning : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. LÄS MER

4. 3. Permanent magnet synchronous machine using ferrite vs rare earth magnets : how do they compare?

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Nikhil Manakshya; [2021]
   Nyckelord :Vehicle requirement; drive cycle; ferrite magnet; demagnetisation; environmental impact.; Fordonsbehov; körcykel; ferritmagnet; avmagnetisering; miljöpåverkan.;

   Sammanfattning : Permanent magnet synchronous machines (PMSM are considered as viable options for automotive and traction applications. Rare earth magnets such as Neodymium Iron Boron (NdFeB is the most common choice in the PMSM for electric vehicles to achieve high power density machines. LÄS MER

5. 4. Communication Channel Measurement and Modeling for Inductive Wireless Power Transfer
