Contents
1. Magnetism of matter. Hysteresis loop and the saturation magnetization.
Origin of the magnetic moment and origin of magnetization of materials: exchange interaction, ferromagnetism, spontaneous magnetization. Magnetic anisotropy. Magnetic domains, magnetic domain walls. Magnetization processes: magnetization rotation, magnetic domain walls displacement, hysteresis loop and their parameters, saturation magnetization and its dependence with temperature: Ms(T).
2. Permanent magnets.
Characteristic parameters of a magnet: coercive field, remanence, product BrHc. Hard magnetic materials: high magnetic anisotropy, pinning of magnetic domain walls. Materials for permanent magnets: high magnetization, high magnetic anisotropy, high Curie temperature. Influence of shape of a magnet: magnetostatic energy.
3. Magnetomotive force (strength of magnetic tension)
Magnetic circuit: magnetomotive force, reluctance. Coupled magnetic circuits: series reluctances, parallel reluctances. Magnetic circuit for a magnet: demagnetizing field, magnetic field in the gap, magnetic energy in the gap. The product (BH)max
4. Electromagnetic waves.
Maxwell’s equation: deducing the electromagnetic wave, EMW, function. EMWs in dielectric media, EMWs in conductors. Properties of electric field and properties of magnetic field in EMWs. Radiation of EMW by an electric dipole: power of radiation and resistance to radiation.
5. Transmission of electromagnetic waves in a media: transmission lines, TEM mode propagation.
General properties of TEM Transmission lines: two conductors TEM transmission lines. Different type of two conductors TEM transmission lines: parallel plate lines, two-wire lines, coaxial lines.
