Diagrams of mode cut-off characteristics for the transversal transmission of the (a) long slot and (b) short slot. The E-field distribution contours for the (c) short and (d) long slot in BPSWS, and for the (e) long slot in MPSWS. High-frequency characteristic parameters (f) Qe and Q0; (g) M2R/Q and frequency) as a function of the length ratio α.
