TLDR
In this article, the authors studied the transmission problem of an electromagnetic pulse with given transversal structure passing through a waveguide converter from TM01 to TE11 mode of circular waveguide.Abstract:
We study a transmission problem of an electromagnetic pulse with given transversal structure passing through a waveguide converter from TM01 to TE11 mode of circular waveguide. Using FDTD numerical simulation method we have investigated mode structure of the pulse at the output of the converter and its dependence on pulse length at the input. Also we have obtained frequency characteristic by calculating Fourier response for a pulse with wide spectrum.read more

Numerical solution of initial boundary value problems involving maxwell's equations in isotropic media
Abstract: Maxwell's equations are replaced by a set of finite difference equations. It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is given of the scattering of an electromagnetic pulse by a perfectly conducting cylinder.
