On Uniform Multimode Transmission Lines

From these results, it can be seen that the approximations made forthe calculation of anaccelerating factor are very good. ln each case we have tested, we have obtained an important amelioration either in the computational time or in precision of calculation, often for both. The precision of the finite-differences method is sufficiently good, as can be seen by comparison with results given by others. We have used two types of results. The first ones arethoseobtained by Cohn’s formulas [11]. In our program, making e,=l and
