Abstract :
Magneto-inductive waves are formed on regular arrays of magnetically coupled resonant circuits when signals close to the resonant frequency of the array are applied. They are a new type of slow wave with useful and interesting properties including offering the possibility for high bandwidth, short range, secure data transmission. A two dimensional array of resonators, which may be fabricated on a flexible membrane forms a convenient near field coupled local communication medium which suitably equipped devices can usefully exploit. Because the nature of the excitations in the resonators is magnetic, this system lends itself to inductively coupled short range terminals which can induce magnetoinductive waves in the surface enabling secure, non radiative (and hence largely license free) data transfer.
