摘要：

In regard to the FDTD analysis of a waveguide bandpass filter, a method of processing time series FDTD data for the Fourier transform is discussed in conjunction with boundary processing near conductor corners, and a new method of processing the FDTD data is proposed. When this method is used, the total computation time for all FDTD processing is reduced by more than 60%. By a calculation for the iris-coupled waveguide bandpass filter, it is confirmed that the new grid arrangement method is as accurate as the corner correction method and is more accurate than the conventional grid arrangement method.
