### Course description and aims

This course focuses on direct solution to Maxwell's equation, diffraction and scattering of electromagnetic wave and antennas. Topics include the derivation and the interpretation of solution to wave equation, field equivalent theorem, scattering in cylindrical coordinate system and its interpretation, antenna parameters and operating principle of basic antennas. By combining lectures and reports, the course enables students to understand the analysis methods of electromagnetic wave and their interpretations and the operating mechanisms of various antennas.
The course follows electricity and magnetism, electromagnetic fields and waves and waveguide engineering and gives students deep interpretations on radiation and scattering of electromagnetic waves and antenna operations and is followed by advanced courses such as guided waveguide circuit theory, electrical modelling and simulations and RF measurement engineering.

### Student learning outcomes

By the end of this course, students will be able to:
1) Derive wave equation from Maxwell's equation and understand the meaning of its solution.
2) Understand the meaning of field equivalent theorem.
3) Solve scattering problems in cylindrical coordinate system.
4) Understand the meaning of diffraction and scattering of electromagnetic wave.
