“…The hard waveguide can be realized both by loading two parallel walls with a dielectric substrate [17], and with a periodic texture [19], but both these realization have larger losses and much narrower bandwidth than the present gap waveguide. They also do not have any of the other advantages of the gap waveguide described in the introduction.…”

“…The ideal linearly polarized hard waveguides can be miniaturized like the gap waveguide, meaning that the gap waveguide itself has no lower cut-off related to its width and gap height, as long as we are able to realize a parallel-plate cut-off. The hard waveguide can be realized both by loading two parallel walls with a dielectric substrate [5] , and with a periodic texture [6] , but both these realizations have larger losses and much narrower bandwidth than the present gap waveguide.…”

This paper presents the design and experimental verification of the ridge gap waveguide, appearing in the gap between parallel metal plates. It also describes the basic ideas of how local waveguides and transmission lines can propagate along desired paths in the air gap between two metal surfaces. The principle of operation is related to the performance of artificial magnetic conductors, AMC surfaces and soft and hard surfaces. And by evaluating the quality factor, a study and quantification of losses in ridge gap waveguide compared to losses in ideal standard rectangular waveguide is also presented.

“…It has been perceived that the AMC in quasi‐TEM waveguide works with the same physical mechanism as well as two‐dimensional periodic structures. At the resonant frequency of the FSS, the side walls behave as high‐impedance surfaces (artificial magnetic conducting), thus supporting the propagation of a quasi‐TEM mode . However, it has already been demonstrated in [I] that the realization of AMC in quasi‐TEM waveguide is not based on the resonant phenomena.…”

The physical mechanism of quasi‐TEM (transverse electromagnetic) waveguides with frequency selective surface (FSS) walls is established on the basis of an equivalent magnetic current technique in this paper. The equivalent magnetic current distributions in the slots of dielectric surfaces with dipole‐FSS walls and dielectric surface of bare‐slab, as well as hexagonal crystal FSS walls, are presented and discussed. This study shows that the electromagnetic fields in waveguide are mainly radiated from the concurrent magnetic current bands in longitudinal slots. The relationship between the uniformity of electromagnetic fields and the phase variation of longitudinal magnetic currents is discussed. The electrical properties and mechanism of quasi‐TEM rectangular waveguides with slotlines are also investigated to confirm the proposed mechanism. Three categories of periodic structure, which are potentially useful as artificial magnetic conductor, are investigated, and the required conditions to realize quasi‐TEM mode in rectangular waveguide are proposed.
