1. A method of analyzing the absorption behavior of an object, comprising the following steps:
generating at least one electromagnetic signal emitted via at least one antenna such that a fixed spatial electric field distribution is produced,
modulating the electromagnetic signal with a waveform at the fixed spatial electric field distribution to generate a modulated signal which is emitted via the at least one antenna as a forward electromagnetic wave towards the object to be analyzed,
measuring at least one wave quantity of the forward electromagnetic wave,
receiving a backward electromagnetic wave via at least one antenna,
measuring at least one wave quantity of the backward electromagnetic wave, and
evaluating the measured wave quantity of the backward electromagnetic wave and the measured wave quantity of the forward electromagnetic wave by respectively transforming the measured wave quantities to obtain a spectrum of the respective transformation, wherein the spectrum assigned to the forward electromagnetic wave is compared with the spectrum assigned to the backward electromagnetic wave to determine deviations of the spectra from each other on the basis of which the object is characterized.
