Question

In conductors, which two parameters are same? (a) Wavelength and phase constant (b) Phase and attenuation constant (c) Attenuation constant and skin depth (d) Skin depth and wavelength This question was posed to me during an interview. My question is taken from Dielectric vs Conductor Wave Propagation topic in section EM Wave Propagation of Electromagnetic Theory Select the correct answer from above options Electromagnetic Theory questions and answers, Electromagnetic Theory questions pdf, Electromagnetic Theory question bank, Electromagnetic Theory questions and answers pdf, mcq on Electromagnetic Theory pdf,electromagnetic theory book pdf,electromagnetic theory pdf notes,electromagnetic theory lecture notes,electromagnetic theory of light,maxwell electromagnetic theory,electromagnetic theory proposed by,electromagnetic theory engineering physics,electromagnetic theory nptel

Answer 1

Right option is (b) Phase and attenuation constant The explanation is: In conductors, which are considered to be lossy, the attenuation and the phase constant are the same. It is given by α=β= √(ωμσ/2).
