1.	For a dielectric, the condition to be satisfied is(a) σ/ωε > 1(b) σ/ωε < 1(c) σ = ωε(d) ωε = 1I had been asked this question in an international level competition.This intriguing question originated from Lossy and Lossless Dielectrics topic in portion EM Wave Propagation of Electromagnetic Theory
Answer» Correct CHOICE is (b) σ/ωε < 1 To elaborate: In a dielectric, the conductivity will be very less. Thus the LOSS tangent will be less than unity. This IMPLIES σ/ωε < 1 is true.
