| 摘 要： | 基于圆波导的场结构和理想导体边界条件，给出管壁电流分布表达式，然后借助MATLAB语言编程，对圆波导中多种波模的管壁电流分布进行仿真．根据仿真图，容易看出针对横电波最易开缝区为沿φ方向在φ=π／2，3π／2附近，横磁波管壁最易开缝区为沿z纵轴方向也在φ=π／2，3π／2附近．管壁电流分布图仿真对开发规则金属波导图形仿真计算器也很有帮助．

| Abstract: | Based on the field distributions and boundary conditions in metal cylindrical waveguide, the mathematical expressions of current in the wall of the cylindrical waveguide have been deduced. The current of the distribution graphs, for various transverse electric fields or transverse magnetic field wave-modes have been simulated in MATLAB language. It is very easy to see that for TE modes the best slot is parallel to φ-axis at near φ = π/2, 3π/2 regions, but for TM modes the best slot is parallel to z-axis at the same regions to measure the electromagnetic fields closed in the cylindrical waveguide. And the simulations of the current of distribution graphs in cylindrical waveguide can supply some hands to create a calculator simulating the electromagnetic fields in regular metal waveguide. |
