Calculate the phase constant of a wave with skin depth of 2.5 units.(a) 5/2(b) 5(c) 2(d) 2/5This question was addressed to me in a national level competition.Question is from Lossy and Lossless Dielectrics in division EM Wave Propagation of Electromagnetic Theory

Answer» RIGHT choice is (d) 2/5

Easiest explanation: The SKIN depth is the reciprocal of the PHASE CONSTANT and the attenuation constant too. Thus δ = 1/β. On substituting for δ = 2.5, we get β = 1/δ = 1/2.5 = 2/5 units.
