Vinod, If this is an academic exercise, then a list serve is not where you will learn the fundamentals. Put simply, a wire is an inductor and even a capacitor can be used for its parasitic inductance if the frequency is right. Try looking in Pozar's book Microwave Engineering. As well as Roger Harrington's Books and Publications. Some more fundamental ideas can be found in the excellent reference Field and Waves in Communications Electronics. By Ramo Whinery and Van Duzer.
