layer is set to (vii) w = a + h. This design suppresses nearly all coupling to the body (FIGS. 14A- 14D) while minimizing the area of conductive textile required (FIGS. 15A-15B). [00125] According to operations 520 the structure design is simulated for the given and calculated parameters. [00126] In operation 526 the dispersion curve is exported and the wavenumber is read, given the thickness of the textile, tf, the dispersion curve of the structure is obtained by an eigenmode solver with varying h between 0.5/zo and 2/zo, yielding the value for which = , in operation 528. [00127] The simulation may be repeated if < or if > through operation 522 in which h is increased by 2 /20, or through operation 524 in which h is decreased by /20 respectfully. [00128] In some embodiments, in operation 530, the h that gives the desired wavenumber is picked, and in operation 532, all the design parameters are obtained. According to embodiments of the present disclosure, the designed metamaterial textile supports the dispersion curve shown in FIG. 1E and fits the surface plasmon model with parameters ΐ = 4 and = 3.75 X 10 10 rad m$^{_ 1}$. [00129] According to some embodiments, numerical simulations have been implemented. For example, electromagnetic simulations were carried out with CST Microwave Studio (Dassault Systems). Field distributions were calculated using the finite-difference time-domain method using dipole excitation. Materials were assigned properties tex = 1.5 for textiles and ¾ 0dy = 40 for tissue, while the computational body model used an anatomically accurate voxel model (Laura, CST Voxel Family) with resolution of 1.85 X 1.85 X 1.25mm. Dispersion curves were obtained by defining a unit cell of the structure and solving for the eigenfrequencies with periodic boundary conditions in the longitudinal directions and phase shift varying from 0 to . [00130] According to FIGS. 5B-5E, which are dispersion curves as the parameters a, b, d and h, respectively, are varied. Within the design range, the dispersion curve of equation (i) hereinabove is largely insensitive to the geometrical parameters except for h. [00131] According to some embodiments, metamaterial textiles may be manufactured from conductive textile patterns, which were laser-cut (via Universal Laser Systems, VLS 2.30) from adhesive Cu/Ni polyester fabric sheets (Conductive Fabric Tape 86750, Laird Technologies; Conductive Non- woven Fabric 4770, Holland Shielding Systems). In some embodiments, patterns were attached on a cotton-polyester blend athletic shirt for radio- wave device and wireless communication experiments, and a cotton sweater for the wireless powering experiments. [00132] According to some embodiments, the radio -frequency field above the textiles was measured using field mapping experiments to characterize the surface mode. The experiments used an electric field probe from the probe were measured by a spectrum analyser as the probe was scanned 5 mm
