摘要

In summary an example of the numerical solution is demonstrated. The parameters of the waveguide are: radius of an internal conductor a = O,0232[m]; external one b = O.O1[m]; height of the internal conductor ledge above a conducting plane h{sub}1 = O,02[m]; external one - h{sub}2 = O,O[m]; the spatial step h = O,0002[m] is equal to the double time one l. Figure 2 fix energy distribution of an electromagnetic field in a near zone of the antenna at the various moments of time.
