GATE EC 2002 Electromagnetics Solution Q 2

A plane wave is characterized by \overrightarrow E=\left(0.5\widehat x+\widehat ye^{j\pi/2}\right)e^{j\omega t-jkz}

This wave is

(a) linearly polarized

(b) circularly polarized

(c) elliptically polarized

(d) unpolarized

Ans : c)

Explanation

We can observe from the equation of the wave that x and y components are not equal. So the polarization must be elliptical.
