Studying Pulsed Operation Modes of Irregular Coaxial Lines with Combined Distributed and Lumped Irregularities

摘要

The problem of propagation and transformation of electromagnetic pulses with the TEM initial structure in irregular coaxial transmission lines containing combinations of distributed and lumped irregularities is formulated, and a numerical algorithm for solving this problem is presented. The problem is formulated and solved in the time domain using nonstationary waveguide equations. Numerical examples are presented for lines containing both distributed smooth irregularities extended along the line axis and various lumped irregularities. The attainability of high calculation accuracy (with errors of ～0.03% and lower) and control over calculation error is demonstrated.
