The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Wide-Band Slot Antenna Arrays With Single-Layer Corporate-Feed Network in Ridge Gap Waveguide Technology (2014, background): “These guiding structures thereby define three different gap waveguides or transmission lines, referred to as ridge, groove and microstrip gap waveguides [15].”
Narrow-Band Microwave Filter Using High-Q Groove Gap Waveguide Resonators With Manufacturing Flexibility and No Sidewalls (2012, methodology): “The articles [5]–[9] treat the ridge gap waveguide, but the gap waveguide technology can also be used to realize groove gap waveguides and microstrip gap waveguides [10].”
Design and Fabrication of a High-Gain 60-GHz Corrugated Slot Antenna Array With Ridge Gap Waveguide Distribution Layer (2016, background): “The gap waveguide technology introduced in [25-28] overcomes the problem of good electrical contact associated with mechanical assembly, by making use of a texture in one of surfaces that creates a magnetic wall (parallel-plate cut-off).”
2$\times$ 2-Slot Element for 60-GHz Planar Array Antenna Realized on Two Doubled-Sided PCBs Using SIW Cavity and EBG-Type Soft Surface fed by Microstrip-Ridge Gap Waveguide (2014, background): “Based on this principle three different versions of gap waveguides called ridge, groove and microstrip gap waveguides were presented in [8] and verified experimentally in [9], [10] and [11], [12], respectively.”
