We theoretically propose the concept of loading microwave waveguides with periodic arrays of dielectric elements that emulate the electromagnetic response of two-dimensional metasurfaces. We focus on the case study of a metasurface composed of dielectric cuboids, which is designed to exhibit a strong toroidal dipole resonance in the microwave X-band. Standard waveguides are then loaded with one-dimensional arrays of the cuboids, such that they reproduce the resonant characteristics of the reference infinite metasurface. It is demonstrated that parallel-plate and rectangular waveguides retain almost the same properties on resonance, while the main attributes are also preserved in standard impedance-matched microstrip lines.
