Truncation of open boundaries of cylindrical waveguides in 2.5-dimensional problems by using the convolutional perfectly matched layer

Abstract

In order to solve the problem of truncating the open boundaries of cylindrical waveguides used in the simulation of high-power microwave (HPM) sources, this paper studies the convolutional perfectly matched layer (CPML) in the cylindrical coordinate system. The electromagnetic field's finite-difference time-domain (FDTD) equations and the expressions of… (More)
