摘要
应用波导理论和有限差分法(FDM)原理,计算了方同轴线高次模TE10模的截止波长及场结构.计算结果表明该方法精度高、通用性强,可用于微波传输线工程方面的研究设计.
A research on the cutoff-wavelength and field-construction of higher order modes in square coaxial lines is carried on with concrete analyses of different boundary conditions by FDM method. Taking TE10 as an example, we have got cutoff-wavelengths and electric potentials by FDM method and MATLAB.
