An apparatus is described for achieving at least one of inspecting and positioning of an object, that comprises: an array adapted to generate continuous wave energy of a single frequency, to transmit the wave energy to an interaction region where it interacts with the object, the array includes waveguides to transmit the energy in both directions to and from the objects. It includes sensor means comprising spaced-apart sensors disposed to receive the wave energy at places after interaction with the object. The sensor means are adapted to produce electric signals representative of the received wave energy. The array comprises a transducer to generate the continuous wave energy which is transmitted by a waveguide of waveguides to the interaction region. The array comprises coupling volume to achieve enhanced coupling between the waveguides and the transducer and the sensor means; means for processing the electric signals into at least one of amplitude and phase information for each sensor of the sensor means; and means for analyzing the at least one of amplitude and phase information from each sensor of sensors into at least one of a geometric characteristic and an electromagnetic characteristic of the object.
