Abstract
A method for deriving physical properties of a workpiece. The method comprises the steps of sampling an electromagnetic wave packet representative of workpiece properties and comprising encoded scattered wave information derivable from a multi-pole interactive coupling between a probe tip and the workpiece; decoding said electromagnetic wave packet by interrogating at least one of its phase and amplitude information; and, correlating this information to referent physical-chemical properties of the workpiece.
