Radio-wave confinement on metamaterial textiles for wireless sensor networking

A method for designing a metamaterial textile for providing a wireless sensor network, said method comprising:

• providing a metamaterial textile comprising:
• a sheet of metamaterial textile cut into a comb shape comprising a long base with a plurality of metamaterial textile teeth extending along and from the base, wherein a gap is present between every two adjacent teeth;
• providing wireless sensor network via propagation of radio-surface plasmons wave along the comb shaped metamaterial textile;
• and
• controlling height of the radio-surface plasmons wave by changing number of the metamaterial textile teeth, and by changing dimensions of the metamaterial textile teeth and dimensions of metamaterial textile gaps.
