1. A tomographic system comprising:
at least one source of electromagnetic energy that generates an electromagnetic field;
at least one transmission line operably associated with the at least one source of electromagnetic energy and configured to guide the electromagnetic field to propagate in a spatial direction along a prescribed path, the at least one transmission line constituted by electrical conductors disposed externally of and facing the prescribed path and extending contiguously alongside the prescribed path, whereby the electromagnetic field propagates passively from region to region of the prescribed path in the spatial direction; and
electronic means for taking measurements of the electromagnetic energy, indicative of impedance, at each of different locations along a length of each said at least one transmission line as the electromagnetic field generated by the at least one source propagates in the spatial direction along the prescribed path, and
wherein the system is configured to modulate a speed of propagation of the electromagnetic field in the spatial direction along the prescribed path to include a speed at which field lines of an electric field of the electromagnetic field extend in directions orthogonal to the spatial direction.
