F. Mesa et R. Marques, LOW-FREQUENCY LEAKY REGIME IN COVERED MULTILAYERED STRIPLINES, IEEE transactions on microwave theory and techniques, 44(9), 1996, pp. 1521-1525
This work studies the low frequency leakage of power in covered multil
ayered striplines including the possibility of several conductors on d
ifferent interfaces. The appearance and features of the lateral radiat
ion is discussed, assuming that only one parallel-plate waveguide mode
is above cutoff, Comparison with quasi-TEM results shows that some le
aky waves behave like quasi-TEM modes with radiation losses. Lateral r
adiation and ohmic conductor losses are also compared.
