In a particular embodiment, a solid immersion lens includes meta-material
slabs formed from multiple layers of at least two different compositions.
Each meta-material slab has a first effective index of refraction. The
meta-material slabs are adapted to propagate an evanescent wave in a
direction parallel to an axis to form a cone-shaped wave along the axis.
The solid immersion lens further includes a core sandwiched between the
meta-material slabs along the axis and having a second index of
refraction that is less than the first effective index of refraction. The
core directs surface plasmons that are excited by the cone-shaped wave to
a focused area coincident with the axis.
