The current chapter treats transmission lines in the frequency domain. The behavior of voltages and
currents on the line behave as plane waves propagating along the line. Many of the relations in chapter

This chapter takes up the issues of transmission, reflection and refraction of plane waves at the
interface between two different media. The dominant quantities are the reflection and transmission
coefficients at interfaces between med
