Answer to Problem 12.1P
The percentage of the incident power density transmitted into the copper is
Explanation of Solution
Given:
A uniform plane wave in air
Concept Used:
First, we find out the intrinsic impedance for the given conductor (copper in our case).
For a good conductor like copper, the intrinsic impedance is,
Then, we calculate the reflection coefficient by using the below formula,
