What are the similarities and differences between wave impen

What are the similarities and differences between wave impendence and characteristic impedance?

Solution

CHARACTERSTIC IMPEADANCE: during the traveling, impedance offred to the line is called as characterstic impedance or surge impedance

zc = zs = sqrt of L/C

the si unit of impeadnce is ohm it is purely real ie, there is no imaginary component it appears as a resistance in nature

WAV IMPEADANCE: the wave impeadance of the electromagnetic wave is the ratio of transverse components of the electric and magnetic fields

for transverse elecromagenatic plane wave traveling through a homogenius medium, the ave impeadnce is everywhere eual to intrinicis impeadance of the medium

for plane wave traveling through emty space, the wave ipmeadncce is equal to impedance of free space it also units have ohm
