Abstract :
The method of lines is extended to analyze planar waveguides with open boundaries. The efficiency of using absorbing boundary conditions is demonstrated by the calculation of the effective permittivity of a single microstrip line. The results show that the boundaries may be placed closer to the guiding structure whereby the discretized area and the corresponding matrices become smaller.<>
