Q2. In one of our assignment problems we saw that the relative permittivity of a metal can be written as: ,(w) = (1-). Plot e, (w) as a function of frequency. (b) Under what condition will this metal act as a perfect reflector? (c) Using the given expression of e, (w), show that if the condition of part (b) is satisfied, the metal ll act as a perfect reflector. %3D
