Abstract: Disclosed is a system for detecting an internal object in a body. The system includes at least one antenna pair including two antennas which are adapted to be symmetrically positioned around the body in relation to a line of symmetry. The system is adapted to transmit microwave signal into the body which are reflected and/or scattered from the internal object. The system is adapted to receive the reflected and/or scattered microwave signals, and to compare the received microwave signals at the symmetrically positioned antennas. The system is adapted to detect the internal object or a change in an already detected internal object when there is a difference between the received microwave signals at symmetric antenna pairs. The difference is related to the different dielectric properties between the internal object and the body.

Abstract: A microwave absorbing materials or gel is disclosed. In some examples, the material can be used in communication, radar, or industrial applications or to reduce the cross section of aircrafts or ships. The gel can be used as an absorbing material is to dampen microwaves. For example, to reduce coupling between antennas, shielding of measurement system to remove disturbances from internal or external error sources, provide a matching between the antenna and the body. The absorbing material can be manufactured as a flexible and moldable gel from polymers, water, and mineral salt. By altering the ratios of the content different damping and mechanical properties of the gel can be obtained. The surface of the material is modified to densify the surface and to reduce the surface slipperiness, avoid evaporation from the gel and to enable disinfection of the surface.
