Abstract
Abstract A device to detect the presence of a target material comprising a source module and detector module. The source module includes a generator to producing a source signal corresponding to a characteristic frequency of the target material. The detection nodule detects a location of the target material wherein the detection module detects an interference signal generated between the source signal and a signal generated by target material caused by exposure to the source signal. The device uses frequencies between 10 MHz and 1.3 GHz
