Claim Text:
1. A method for electromagnetically characterizing an object at a given frequency, characterized in that said object is placed in a chamber whereof at least some of the walls have a low absorbance at said frequency, one of the chamber walls being equipped with an array of antennas, each antenna being able to transmit one and receive several electromagnetic waves according to a first polarization and a second polarization orthogonal to the first, said method comprising the following steps: when said object is not present in the chamber, measuring a first set of complex values (μ when said object is present in the chamber, measuring a second set of complex values (μ outputting an electromagnetic characteristic of said object by subtracting the complex values of the first set from the corresponding complex values of the second set to obtain a list of corrected complex values, said electromagnetic characteristic being obtained as at least one sublist of said list of corrected complex values.
