Question:
Which one of the following field patterns represents a TEM wave traveling in the positive \( z \)-direction?
Which one of the following field patterns represents a TEM wave traveling in the positive \( z \)-direction?
Show Hint
In a TEM wave, the electric and magnetic fields are mutually perpendicular and also perpendicular to the direction of propagation.

- \( E = +3\hat{y}, H = -4\hat{z} \)
- \( E = -2\hat{y}, H = -3\hat{z} \)
- \( E = +2\hat{z}, H = +2\hat{y} \)
- \( E = -3\hat{y}, H = +4\hat{z} \)

The Correct Option is C
Solution and Explanation
For a TEM wave, the electric field \( \vec{E} \) and magnetic field \( \vec{H} \) are perpendicular to each other and to the direction of wave propagation. In this case, the electric field \( E \) along \( \hat{z} \) and the magnetic field \( H \) along \( \hat{y} \) represent a typical TEM wave propagating in the \( +z \)-direction.
