Abstract
A transponder including a first resonator and a series of one or more second resonators with coupling of evanescent waves exhibiting at least one first resonant mode and one second resonant mode, said first resonator being connected via a first port, to a first means allowing an interrogation, wherein said second resonators are connected via at least one second port, to at least one variable load element capable of modifying coupling conditions of the resonant modes and consequently a response measured on said first port.
