This paper reports on a suitable formulation of the spectral-domain/integra
l-equation method for the quasi-TEM analysis of hybrid strip/slot-like plan
ar lines. The free surface charge distribution is used as an unknown on the
strip like interface, whereas the electric field is used on the slot-like
region. This formulation allows us to reduce the number of basis functions
and makes possible a unified treatment of the problem. A single type of bas
is functions is used, leading to a quasi-analytical evaluation of the Galer
kin matrix entries. The performance of the method is illustrated with a pra
ctical example structure useful for coupler design.
