1. A scanning microscope for imaging a sample, the scanning microscope comprising:

  • generator means for generating electromagnetic energy;

    applying means, receiving the electromagnetic energy from the generator means, for applying the electromagnetic energy to the sample to form a field of electromagnetic radiation around the sample;

    a probe, for placement in proximity with the sample, for receiving the electromagnetic radiation from the sample, comprising a resonant coaxial transmission line with an open end for receiving the electromagnetic radiation from the probe;

    detector means for detecting the electromagnetic radiation received by the probe and for outputting an imaging signal; and

    means for analyzing the imaging signal.
