Abstract: Example systems disclosed herein include a pathway-article assisted vehicle (PAAV) that utilizes an autonomous navigation system for navigating temporary zones on vehicle pathways. The PAAV includes at least image capture device and a computing device. The image capture device generates an image that includes an indication of a temporary zone on a vehicle pathway, such as a pathway article proximate to the vehicle pathway that indicates the temporary zone. The computing device processes the image to obtain the indication of the temporary zone from the image, such as a code on the pathway article, and modifies, based on the indication of the temporary zone, a mode of autonomous operation of the PAAV while operating within the temporary zone on the vehicle pathway.

Abstract: At least some aspects of the present disclosure feature a waveguide for propagating an electromagnetic wave. The waveguide includes a base material and a plurality of resonators disposed in a pattern, the plurality of resonators having a resonance frequency. Each of the plurality of resonators has a relative permittivity greater than a relative permittivity of the base material. At least two of the plurality of resonators are spaced according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.

Abstract: Techniques are described for a lens containing high dielectric resonators. In one example, a lens comprises a substrate for propagating an electromagnetic wave and a plurality of resonators dispersed throughout the substrate. Each of the plurality of resonators has a diameter selected based at least in part on a wavelength of the electromagnetic wave and is formed of a dielectric material having a resonance frequency selected based at least in part on a frequency of the electromagnetic wave. Each of the plurality of resonators also has a relative permittivity that is greater than a relative permittivity of the substrate. At least two of the plurality of resonators are spaced within the substrate according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.
