Circuit model of the proposed structure under the y-polarization.

(a) Origination of the inductor and capacitor when the electric field is polarized along the y-direction. (b) Equivalent LC circuit model for the y- polarization. (c) Electric field distributions and (d) volumetric current flows at f₃ = 3.5 GHz (zero point of Z_y). (e) Electric field distributions and (f) volumetric current flows at f₄ = 5.3 GHz (polar point of Z_y). (g) Electric field distributions and (h) volumetric current flows at f₅ = 13.8 GHz (zero point of Z_y).
