Patent ID: 8618817

Claim:
A device comprising: a measuring path having a line system that includes at least two elementary cells situated along the measuring path, each elementary cell comprising an electrical path from at least one input to at least one output, wherein the elementary cells each comprise at least one capacitive element; a generator for generating an electrical or electromagnetic signal that is supplied to the input of a first elementary cell, the output of the first elementary cell being connected to the input of a second elementary cell such that said first and second elementary cells are connected in series, and the capacitive element of the respective first and second elementary cells being situated in the electrical path of the first and second elementary cells, and in each case at least one inductive element connects the electrical path of the first elementary cell and the second elementary cell to an electrical ground; and an evaluation device for analyzing an output signal of the measuring path, wherein the evaluation device is configured to determine at least one parameter of a medium that is introduced into the measuring path such that an electrical property of the capacitive element of an elementary cell is modified by the medium, and wherein an electromagnetic field is coupled into and/or out of the medium by introducing the electrical or electromagnetic signal into the measuring path.
