1. A method, comprising:

  • determining electromagnetic parameters that define a negative refractive index in a spatial region, the electromagnetic parameters providing an axial magnification substantially less than one for an interior focusing region within the spatial region;

    selecting one or more positions of one or more electromagnetic sensors within the spatial region; and

    configuring an artificially-structured material having an effective electromagnetic response that corresponds to the electromagnetic parameters in the spatial region.
