Abstract
With high field confinement and a constant input impedance of ~50 W for a wide range of frequencies in addition to their single layered, low profile and flexible configurations, the SSP structures are able to provide a plausible platform for cost effective and compact microwave circuits. It is necessary to design an appropriate transition to couple the SSP modes to the conventional transmission lines and realize the slow-wave transmission lines (SW–TLs). In this chapter compact mode converters are proposed to provide gradual impedance, momentum, and polarization matching from guided waves to spoof surface plasmons and form efficient SW-TLs. The designed SW-TLs are studied as parts of microwave circuits and their excellent performance is verified numerically and experimentally.
