摘要:
Various embodiments of the present invention are directed to dynamically and electronically reconfigurable optical devices that can be operated as a lens or prism for incident beams of electromagnetic radiation. The optical devices include a phase-modulation layer (1501) disposed between first and second nanowire layers (1502,1503). Overlapping nanowires can be electronically addressed to implement a selected effective refractive index pattern of one or more regions (1510) of the phase-modulation layer, such that each region refracts a portion of an incident beam of electromagnetic radiation having a wavelength of interest in order to focus, diverge, or bend the incident beam.

An emissions control system for a vehicle having an exhaust system with an exhaust gas conduit and a catalytic converter configured to receive exhaust gas from an engine is provided. In one example implementation, the system includes an engine controller configured to control the engine to adjust an air to fuel ratio (lambda) thereof. The engine controller is configured to operate the engine with at least one of the following lambda control strategies (i) a first control strategy comprising operating at a first reference lambda modified by a first percent kick, and a first rich lambda lag time shorter than a first lean lambda lag time, and (ii) a second control strategy comprising operating at a second reference lambda modified by a second percent kick, and a second rich lag time longer than a second lean lambda lag time, to thereby simultaneously meet predetermined NOx and CO emissions targets.

A metamaterial inclusion structure (MIS), a metamaterial and a method of producing an optical magnetic response employ interspersed plasmonic and dielectric materials. The MIS includes first petals of a plasmonic material and second petals of a dielectric material that alternate at a surface and along a periphery of the MIS. The MIS exhibits the magnetic resonance when illuminated by an optical signal at an optical wavelength. The optical signal has a magnetic field component that is parallel with an interface between the first petals and the second petals. The metamaterial includes a plurality of the MIS arranged in an array and provides an optical magnetic susceptibility at the optical wavelength. The method forms the MIS with the alternating petals and includes illuminating the MIS with the optical signal.
