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

In the present paper, the problem of externally excited exponential transmission line has been solved analytically in frequency domains using a simple approach. Then step lines approximation as a first order approximation for the problem of externally excited nonuniform 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 some useful results are obtained to show when the two methods are equivalent.
