Subsequent to Radio Wave Engineering I, this course provides fundamental topics related to radio waves, which are crucial
in information transmission through communication systems.
First, the course expands on the concept of voltage and current waves to introduce the properties of electromagnetic waves.
Next, students will acquire an understanding of skin effect and the resistance at radio frequencies in transmission lines, which are essential for engineers working with high-frequency communication systems. Finally, the course will cover higher-order mode transmission waves, including electromagnetic field transmission in waveguides.

This course aims for students to understand the fundamental properties of electromagnetic waves, which are crucial for mobile
communications such as 5G and wireless LAN technologies such as Wi-Fi. In addition, students will acquire basic knowledge
of antenna theory and radio wave transmission, which are essential for the design and analysis of wireless communication systems.
- At the end of the course, students will be able to
(1) understand that the voltage and current of a transmission line are in fact integrated amount of electromagnetic fields propagating along the line, - (2) understand why the capacitance and inductance derived for static fields in a transmission line can be used in analysis of the line for dynamic fields,
- (3) understand that we can evaluate the resistance of a transmission line, taking into account skin effect, and
- (4) acquire the characteristics of a waveguide on the basis of higher-order modes of a parallel-plate transmission line.
