Farr, Everett George 2014-12-15T19:05:00Z 2014-12-15T19:05:00Z 10000-01-01 1985 1985 In this report, a number of topics are considered that concern printed circuits and printed circuit discontinuities. First, propagating and evanescent modes of a shielded microstrip are calculated using the spectral Galerkin technique. The characteristic impedance and field configurations of these modes are also calculated. These modes are then used in a mode matching technique, in order to calculate the scattering from abrupt discontinuities in the microstrip. Results are given for various configurations of single and cascaded discontinuities. Next, the singular integral equation technique is used as an alternative to the spectral Galerkin technique, to calculate modes in a shielded microstrip. These results are compared to those generated by the spectral Galerkin technique. Finally, the coupling between multiple transmission lines is considered, by using the coupled-mode theory. Results for the propagation constants of the various modes of propagation, as well as for the transfer of current from one line to the next, are presented.
