1. A method, comprising:

  • negatively refracting an electromagnetic wave at a surface region, the surface region defining a surface normal direction;

    spatially contracting the refracted electromagnetic wave along a contraction direction, the contraction direction corresponding to the surface normal direction, wherein the negatively refracting and the spatially contracting provide a focusing region for the refracted electromagnetic wave; and

    sensing the electromagnetic wave at one or more locations within the focusing region;

    wherein the sensing includes sensing with at least one antenna.
