Abstract

In this paper the finite difference time domain technique with the berenger’s perfiectly matched layer (PML) is applied for the analysis of side coupled microstrip filter. The effect of the OML thickness is studied. Numerical results for the time domain response, the scattcring parameters, and the input impendance are obtained. Good improvement of the present results over that published and obtained by the equivalent circuit model method are found.
