    摘要： The present disclosure provides an autonomous biomonitoring system in lotic ecosystems, such as streams. A central design concept of autonomy is capturing aquatic organisms from their natural habitat and entraining them through an analyzer with an imaging unit. The system provides a collector for a sampling aqueous mixture that can flow through a screen to a sediment trap that is coupled to a pump that discharges the aqueous mixture into a staging tank. The staging tank is coupled to a flow-through analyzer and can continuously buffer and control the volume of aqueous mixture flow through the analyzer, and then the aqueous mixture is discharged. In at least one embodiment, the system allows continuous monitoring over a period of time. The system can transmit real time data to a remote location for data accumulation. The system can further provide remote movement of the collector for sampling at multiple remote locations.

    摘要： The present disclosure provides devices, systems, circuits, and effective methods for advanced optical applications using plasmonics and ENZ materials. The disclosure provides for enhancement of the optical tunability of phase and amplitude of propagating plasmons, nonlinear-optical effects, and resonant network in optical fiber tip nanocircuits and integrates the tunable plasmonic and ENZ effects for in-fiber applications to provide optical fiber with high operating speed and low power consumption. The invention yields efficient coupling of a plasmonic functional nanocircuit on the facet of an optical fiber core. The invention also can use gate-tunable ENZ materials to electrically and nonlinear optically tune the plasmonic nanocircuits for advanced light manipulation. The invention efficiently integrates and manipulates the voltage-tuned ENZ resonance for phase and amplitude modulation in optical fiber nanocircuits.

    摘要： The disclosure provides a microwave system developed to measure properties of fluidic materials incident upon a surface using a phase response of multiple microstrip transmission lines, generally over an ultra-wideband excitation. The system can include a series of parallel planar transmission lines as waveguides that are coupled to an insulator layer and a conductor as a formed-to-fit or flexible insulator layer, an ultra-wideband RF transceiver measuring phase angle, and a processing computer. The system can directly measure electrical permittivity in the microwave frequency band. This measurement can be processed to determine the presence of a homogeneous or heterogeneous fluidic material on a surface to which the transmission lines are coupled, the presence of a phase change in the fluidic material, and potentially the presence of other fluidic materials, depending on differences in permittivity between the fluid materials. In some embodiments, a thickness of the material can be also be provided.
