N2 - An accurate analytical model of the metasurface-loaded waveguide is presented in this paper. Firstly, a capacitive metasurface is proposed, which consists of subwavelength periodically positioned metallic cylinder posts. By changing the insertion depth of the metasurface in the middle plane of the waveguide, the propagation constant and cutoff frequency of the waveguide can be tunable and reconfigurable. Counterintuitively, the proposed capacitive metasurface demonstrates itself a lumped and non-dispersive capacitor. Furthermore, a simple but accurate analytical dispersion relation is derived for the metasurface-loaded waveguide and validated by numerical simulation. A prototype is fabricated to validate the proposed concept. The proposed method provides an avenue for reconfiguring the cutoff frequency and propagation constant of the waveguide. The derived analytical model has significant instructive meaning for predicting the propagation characteristics of the metasurface-Ioaded waveguide.
