Abstract :
An analysis of coplanar waveguides (CPW) by the time-domain finite-difference method is discussed. The waveforms propagating along a coplanar waveguide excited by a Gaussian pulse are found in the time domain. After the time-domain computation is done, the frequency-domain parameters, such as the effective dielectric constant and the complex characteristic impedance, are calculated by Fourier transformations. The results agree well with the available theoretical and experimental data over a wide frequency range.<>
