A dispersive boundary condition for microstrip component analysis using the FD-TD method

A dispersive absorbing boundary condition (DBC) which allows the dispersion characteristics of waves to be used as a criterion for designing absorbing boundary conditions is presented. Its absorbing quality is superior to that of the presently used Mur's first-order boundary condition for microstrip component analysis, and its implementation is much simpler when compared to that of the super boundary condition treatment. Due to the significant performance improvement of the new boundary condition, the memory requirement can be reduced greatly when applying this boundary condition to microstrip component analysis.<
