An uniform plane wave incident normally on a plane surface of dielectric material is reflected with a VSWR of 3 what is the percentage of incident power that is reflected?
-
- 10%
- 25%
- 50%
- 75%
Correct Option: B
Percentage of reflected power given by
P– R = | Γ |2 Pi+
| Γ = | ⇒ | = | |||
| 3 + 1 | 4 | 2 |
| PR– = |  |  | 2 | Pi+ | |
| 2 |
so percentage reflected power
| × 100 = | × 100 = 25% | ||
| Pi | 4 |
