A new fabrication approach, self-aligned membrane projection lithography, is used to create composite split ring resonators with a resonance near 10 μm. The composite resonators are oriented on the interior face of approximately-spheroidal cavities, and hence represent the first instance of fabrication of micrometer-scale SRRs with out-of-plane current flow.
