Concept:
The waves are used for the transportation of energy or information.
Characteristics of a plane wave in good conductors.
In a good conductor σ >> ωϵ 
σ ≈ ∞, ϵ = ϵ0, μ = μ0μr 
Calculation:
Given ϵr = 1, μr = 20, σ = 3 S/m and 
Hence the given medium is a good conductor.
In a good conductor the values of α and β are:
α = β = 61.39
