2. (a) Consider the propagation of a plane electromagnetic wave in a conductor. Show that the wavenumber, k, as a function of a, is given by the dispersion relationship ex ωε ωε where σ is the conductivity, μ is the permeability and ε is the permittivity of the conducting medium. (Hint: start with Maxwell's equations, and develop an equation of the form, V" E -k 2 E ). (3 marks) (b) Write down an expression for the physical electrical field...
[132 2 2 3 4 17 marks] Question 4 A plane wave is travelling in a vacuum in the +z-direction with wavenumber k and angular frequency . It is linearly polarised in the x-direction, and has electric field given by E(t, z) Eo Cos(kz - wt)f This wave is normally incident on a perfectly electrically conducting, semi-infinite slab in the region z > 0 and the resulting field in vacuum (z < 0) is a superposition of the incident and...
please can you answer All of these questions? thank you Part 1. Exercise Questions (Have to be submitted ) State Coulomb's law and give the mathematical expression. b) Write the definition of electric field strength. What is its SI unit? (Use your own words). c) Define electric displacement vector. What is its SI unit? i.Does the electric displacement vector due to a given charge distribution depend on the properties of the medium? Does the electric field intensity due to a...
