ABSTRACT:
Wireless tags with a plurality of non-equivalent current pathways altered to collectively represent encoded information, each of which responds differently to an interrogation signal. The element is subjected to a signal stimulating the current pathways, each of which contributes to an overall element response. The information may be recovered from the salient features of this overall response. These salient features include resonant frequency, amplitude, relative peak position, relative peak amplitude, damping, and Q factor.
