Abstract :
A novel Finite Difference Time Domain (FDTD) scheme is proposed for the analysis of waveguide components. The method consists of combining the conventional 3D with the 1D-FDTD algorithm resulting from the time domain modal expansion in uniform waveguides. The new algorithm has been validated on a simple test example showing that the same accuracy can be obtained with a substantial improvement in the numerical efficiency
