OSE 5312 FUNDAMENTALS OF OPTICAL SCIENCE Spring 2007 Homework set 5: Due Wednesday, February 14 1. Mg has an electron density of 8.61 x 1028 m-3 and a DC conductivity of σ0 = 2.26 x 107 Ω-1 m-1. Find the plasma frequency and the electron collision time. Find the real and imaginary parts of the dielectric constant and hence the real and imaginary parts of the refractive index at a wavelength of 500 nm. Hence find the reflectance at 500 nm. What is the skin depth at 500 nm? (careful.) What is the skin depth at a wavelength of 600 microns? At 1200 microns? (You can assume that the optical properties of Mg follow the Drude model well, and that there are no bound electron transitions that impact the plasma frequency.)
