2. Magnetostatics
Magnetostatics focuses on magnetic fields in systems where currents are steady (not changing). Important topics include:
- Magnetic Field: The influence of magnetic dipoles and current-carrying conductors on the surrounding space.
- Biot-Savart Law: A formula that calculates the magnetic field generated by a steady current.
- Ampere’s Law: A relationship between magnetic fields and the electric currents that produce them.
3. Electromagnetic Waves
Electromagnetic waves are a crucial aspect of applied electromagnetics. Key points include:
- Wave Propagation: Understanding how electromagnetic waves propagate through different media.
- Maxwell’s Equations: The set of four equations that form the foundation of classical electromagnetism and explain how electric and magnetic fields interact.
- Polarization: The orientation of the electric field vector in a light wave and its significance in communication technologies.
4. Transmission Lines
The study of transmission lines is vital for understanding how signals travel over distances. Key concepts include:
- Characteristic Impedance: A parameter that describes how signals propagate along a transmission line.
- Reflection Coefficient: A measure of how much of a signal is reflected back due to impedance mismatches.
- Transmission Line Equations: The mathematical relationships that describe voltage and current along a transmission line.
