This is a problem on electrodynamics about EM waves in conductors, please see the translation below, you only need to submit part (d), i will sure give you a thumb up if you show your steps :D
Simple model of a metal:
(a). Calculate the dielectric constant for a conducting material by taking the electrons in an external field a motion equation (see the equation below)
The dipole moment by electron is then p = e x and we find the density of polarization P = N p = e E (where N is the number of free electrons per volume)
(b). Calculate the resistance from part a
(c). Discuss the result for the case of copper if we take N = 8 · 10^22 atoms / cm3 and a conductivity at low frequency = 5 · 10^17sec1.
(d). Discuss the eta / m limit and the transparency of a metal at these frequencies. Calculate in addition the pressure on a copper block depending on the frequency (for normal incidence; the pressure is the exchange rate of the pulse per unit of time per area)

This is a problem about linearly polarized EM wave, please see the translation below. You only need to answer the first 2 questions, which are not too much for you. I appreciate and if you keep me posted, i will sure to give you a thumb up :D Suppose this wave is linearly polarized, with ε a unit vector define the direction of polarization and kI = kx the incident wave vector (a). Under what conditions do the vectors kI,...
Please show all your stepsi will sure to give you a thumb up! This is a problem on electrodynamics for EM waves in conductors (Please see the translation attached!) Metals Reflection and phase change: We have one EM wave (see the equation below) with frequency ω incident on a metal plane with high conductivity and a dielectric constant (relative permittivity) with ε =2 (see the number below) For the reflected wave (see the equation E(R)), calculate the difference between the...
