Calculate the skin depth of a material with attenuation constant of 2

1.	Calculate the skin depth of a material with attenuation constant of 2 units.(a) 2(b) 1(c) 0.5(d) 4I got this question during an internship interview.My doubt stems from Lossy and Lossless Dielectrics in portion EM Wave Propagation of Electromagnetic Theory
Answer» Correct choice is (c) 0.5 To explain: The skin depth of a MATERIAL is the reciprocal of the ATTENUATION CONSTANT. Thus δ = 1/α. On SUBSTITUTING for α = 2, we GET δ = ½ = 0.5 units.
