Question

Reflection coefficient is not a function of __________

(a) Material property

(b) Diffraction loss

(c) Wave polarization

(d) Angle of incidence

This question was posed to me in an international level competition.

My question is from Reflection in section Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Correct choice is (b) Diffraction loss

The explanation is: The reflection coefficient is a function of the material properties, and generally depends upon the wave polarization, angle of incidence and frequency of propagating waves. It is a parameter that describes how much of an electromagnetic wave is reflected by an impedance discontinuity in the transmission medium.
