A plane wave propagating through a medium [Er = 8, Vr = 2 and σ = 0] has its electric field given by
. The wave impedance in ohms is—→ ^ E = 0.5 ax e–(z/3) sin (108 t – β2) V/m

- 377
- 198.5 ∠180º
- 182.9 ∠14º
- 133.3
Correct Option: A
Wave impedance of medium is given by
| | n | = | = | ||
| Hys | Hy5 |
| = | n0 = 377 Ω | |
| √μr/εr |
