Select the term below is the best one to describe the polarization of a wave with phasor electric field given by Eˉ=2(a^y​−ja^z​)e−jk0​x( V/m)

The best term to describe the polarization of the wave with the phasor electric field given by:

\[
\vec{E} = 2 (\hat{a}_y - j \hat{a}_z) e^{-jk_0 x} \quad \text{(V/m)}
\]

is **circular polarization**.

### Explanation:
- The electric field has components in the \( \hat{a}_y \) (y-axis) and \( \hat{a}_z \) (z-axis) directions.
- The presence of the imaginary unit \( j \) (or \( i \)) in the \( \hat{a}_z \) component indicates that the \( y \)- and \( z \)-components are out of phase by \( 90^\circ \). 
- When two perpendicular components of the electric field are out of phase by \( 90^\circ \) and have equal magnitudes, the resulting polarization is circular.

Here, \( \hat{a}_y \) and \( \hat{a}_z \) have equal magnitudes (since \( 2 \) is the magnitude for both components), and the phase difference between them is \( 90^\circ \) due to the \( j \) in front of the \( \hat{a}_z \)-component. This results in a circular polarization.

### Tip:
Circular polarization can be either left-handed or right-handed, depending on the direction in which the electric field rotates with respect to the direction of wave propagation.
