Abstract
Embodiments described herein include an apparatus including an antenna and a processor operatively coupled to the antenna. The processor can generate an input signal and send the input signal to the antenna. The antenna can, in response to the input signal, transmit first surface electromagnetic signals along an interface between a first medium and a second medium. The antenna can receive second surface electromagnetic signals in response to the first surface electromagnetic signals being scattered by an object disposed in the first medium. The processor can produce an image of the object based on the first surface electromagnetic signals and the second surface electromagnetic signals.
