COMPARISON OF EXACT ANALYSIS AND STEPLINES APPROXIMATION FOR EXTERNALLY EXCITED EXPONENTIAL TRANSMISSION LINE

In the present paper, the problem of externally excited exponential transmissionline has been solved analytically in frequency domains using a simple approach. thenstep lines approximation as a first order approximation for the problem of externally excitednonuniform transmission lines in general and exponentially tapered transmission line (e'rl)as a special case has been presented. finally the two approaches are compared and someuseful results are obtained to show when the two methods are equivalent.
