The storage density can be further increased by employing asymmetric and polarization-dependent nanostructures. However, further increases in storage density and security capabilities are still vital for the successful implementation of plasmonic metasurfaces as encoding and encryption solutions. Recent progress in infrared hyperspectral imaging has opened up the possibility of covert image encoding. Here, the optical properties of double resonant plasmonic nanostructures are investigated in the mid-infrared. The structures consist of plasmonic nano-antennas that are placed inside resonant plasmonic ring cavities. The associated plasmonic resonances weakly interact, which causes hybridization.

Additional challenges with dense suspensions include particle bridging at the transducer orifice or die and large dead zones of aggregation resulting from the sharp entry angles from piston to die. A downscaled, “disposable” capillary rheometer termed the “miniaturized capillary rheometer” is introduced to address these challenges. This device can be created in a typical lab space at low cost and requires only single grams of sample. To validate the miniaturized capillary rheometer measurements, three different dense suspensions with different particle size and geometry (60 vol% glass microbubbles, 7 vol% fumed silica, and 20 vol% calcium carbonate) are evaluated over a range of shear rates spanning 63–1000 s<sup>−1</sup> and compared to full-scale capillary rheometry.
