for wireless networking and has overall dimensions (2.5 cm width, 8 mm unit cell length) compatible with easy integration with most types of clothing by direct attachment of commercially available, low-cost conductive textiles. [00118] The metamaterial shown in FIG. 5A(l) may support a surface plasmon dispersion of the form: where is the permittivity of the dielectric and 2 is the permittivity of the metal. [00119] Using the Drude model without damping, 2 can be modelled as (ii) 2 = 1 where c is a parameter analogous to the plasma frequency. The metamaterial has a negative permittivity parameter 2 < 0 at frequencies co < co . The resulting dispersion curve lies right of the light line and approaches a horizontal asymptote co = co , where (iii) p = co / J l + is the surface plasma frequency. The parameters $^{c:}$\ and c for the metamaterial textile may be found by fitting the numerically calculated dispersion curve to this model. [00120] The metamaterial textile may be designed by determining the geometrical parameters of the structure to support a surface mode with a desired wavenumber s at the design frequency / o = 2.4 GHz. By scaling the dimensions of the textile with the wavelength, the structure may be designed to support surface modes at frequencies between 10 MHz to 100 GHz. The resulting surface plasmon wavelength is given by p = 2 / s and the decay length (iv) q 1 = 1 / — which determines the distance at which wireless devices may interact with the textile. [00121] According to some embodiments, the method 500 for designing and accordingly manufacturing metamaterial textiles, may comprise the following operations. [00122] In operation 510, the parameters ,/op, and ti are determined. [00123] In operation 5 12, is calculated based on (v) /. p = 2 // • in operation 5 14, the length of the unit cell is set to d = 0.2/. . Simulations show that d has negligible effect on (the design wavenumber of the frequency /o) if it is significantly subwavelength (FIG. 5D), while larger values result in designs that are easier to fabricate. According to operation 516, the parameters of the comb like structure of the metamaterial textile are set as a = 0.5 d and b = 0.75 /. FIGS. 5C-5D illustrate that /k is largely insensitive to a and b but can be tuned over a broad range by h. [00124] According to operation 518, parameter h is initialized to (vi) h = 7 c/(4 6¾ $_{ex}$/o), where tex the relative dielectric permittivity of the textile. In operation 518, the width of the bottom textile
