Question

Which of the following is true for the elliptical polarization?

(a) Ex=Ey, and ∅=π/2

(b) Ex≠Ey, and ∅=π/2

(c) Ex≠Ey, and ∅=π/4

(d) Ex=Ey, and ∅=π/4

I got this question during an internship interview.

I'd like to ask this question from Types of Polarization in division Radiation, Baluns & Polarization of Antennas

Answer 1

Correct answer is (b) Ex≠Ey, and ∅=π/2

Explanation: The locus traced by the extremity of the time-varying field vector at a fixed observational point is called polarization. In elliptical polarization, the electric field components are perpendicular to each other and have unequal magnitude.

Ex≠Ey,and ∅=π/2
