Question

The expression for phase constant is given by

(a) Phase constant β = ωμε

(b) Phase constant ω = με

(c) Phase constant β = ω√(με)

(d) Phase constant β = 1/ωμε

I got this question in an online interview.

Question is from Dielectric vs Conductor Wave Propagation topic in division EM Wave Propagation of Electromagnetic Theory

Answer 1

Right option is (c) Phase constant β = ω√(με)

For explanation: The phase constant is represented as β. It is a complex quantity representing the constant angle of the wave propagated. It is given by  β = ω√(με).
