1.	Permittivity and conductivity are insensitive to ______ for a good conductor.(a) Operating frequency(b) Polarization density(c) Electric field(d) Property of materialThis question was posed to me in an internship interview.The doubt is from Reflection topic in chapter Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile
Answer» The correct ANSWER is (a) Operating frequency The EXPLANATION is: The terms permittivity and CONDUCTIVITY are insensitive to operating frequency when the material is a good conductor. In the case of conductors, it is evident that electric FIELD INSIDE a conductor is zero. That is because free charges reside only on the surface of conductor and not inside.
