Abstract:

The authors presented alternating direction implicit multiresolution time\|domain (ADI-MRTD) formulation, and  implemented  perfect matched layer (PML) as absorbing boundary conditions of ADI\|MRTD method. The application of the ADI\|MRTD method  to the calculations of asymmetrical coplanar waveguide (ACPW) and ultra\|wideband ACPW filter. The  numerical and measured results show the advantages of ADI-MRTD over conventional FDTD method with respect to memory and mesh requirements and execution time, and the numerical result of ADI\|MRTD is in agreement  with FDTD and measured result.

Key words: alternating direction implicit multiresolution time\, domain (ADI\, MRTD), perfect matched layer (PML), asymmetrical coplanar waveguide (ACPW), filter
