Adispersive material has an index of refraction n and an absorption coefficient a at the light frequency w. b) a linear dielectric material with susceptibility xe-2 is inserted in a capacitor which initially had a capaci- c) a current 11 flowing in coil 1 leads to a known flux φ2 through an adjacent coil 2. now 11 is turned off and d) on the surface of a conductor an electromagnetic wave has the complex wave number ka+ib. what is state the complex wave number tance c. what is the capacitance afterwards. a current i2 is passed through coil 2. what is the flux through coil 1? the skin depth?
