The successful application of FD-TD methods to millimetric planar transmission lines presupposes a satisfactory answer to the problem of infinite line termination (Absorbing Boundary Condition ABC) in presence of high frequency dispersion. It is the purpose of this work to evaluate the efficiency of some commonly employed ABC's and to present a technique that reduces reflection error to less than 10\% for microstrip and coplanar line circuits up to and beyond 50 GHz. that is lower than the discretization and round-off errors introduced by the very FD-TD technique. We report some examples of microstrip and coplanar line, comparing results with those obtained by other authors as well as with those of commercial packages and with experimental data.

Abstract
The successful application of FD-TD methods to millimetric planar transmission lines presupposes a satisfactory answer to the problem of infinite line termination (Absorbing Boundary Condition ABC) in presence of high frequency dispersion. It is the purpose of this work to evaluate the efficiency of some commonly employed ABC's and to present a technique that reduces reflection error to less than 10\% for microstrip and coplanar line circuits up to and beyond 50 GHz. that is lower than the discretization and round-off errors introduced by the very FD-TD technique. We report some examples of microstrip and coplanar line, comparing results with those obtained by other authors as well as with those of commercial packages and with experimental data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
