1. A method using electromagnetic energy for obtaining information concerning a characteristic of a substance, comprising:
- generating an ultra-wide band signal having a continuous, broad band frequency spectrum that includes a frequency range for which the substance is responsive to electromagnetic energy;
communicating the ultra-wide band signal to the substance to enable electromagnetic energy to interact with the substance over a broad range of frequencies simultaneously;
acquiring a response signal from the energy interacting with the substance; and
evaluating distortion in the acquired response signal to obtain information concerning a characteristic of the substance.
