Question asked by Filo student
(a) At a particular temperate, silicon is a poor conductor and has a resistivity of 3000 ohm-meter. What is the skin depth for a microwave with frequency ν = 3 x 109 Hz in such a silicon? The dielectric constant of silicon is around 11.7 (b) At a particular temperature, gold is a good conductor and has a resistivity of 2.0 x 10-8 ohm-meter. What is the skin depth for a microwave with frequency ν = 3 x 109 Hz in such a gold? Assume the relative permeability is 1 for both cases.
