Abstract: A waveguide and a communication system including the waveguide are described. The waveguide is configured to propagate an electromagnetic wave having an operating frequency along the waveguide. The waveguide includes a substrate having a first dielectric constant, and an array of spaced apart unit cells at least partially embedded in the substrate and arranged along the waveguide. Each of a plurality of the unit cells in the array of spaced apart unit cells has a first transmission parameter S121 having a lowest resonant frequency Γ1 and includes a dielectric body and one or more electrically conductive layers disposed on and partially covering the dielectric body. The dielectric body has a second dielectric constant greater than the first dielectric constant at the operating frequency and has a second transmission parameter S221 having a lowest resonant frequency Γ2 greater than Γ1.

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.

Abstract: A passive temperature-sensing apparatus, which includes a capacitive sensing element that includes a capacitive sensing composition that includes a ferroelectric ceramic material that exhibits a measurable electrical Curie temperature that is below 30 degrees C. The capacitive sensing composition exhibits a negative slope of capacitance versus temperature over the temperature range of from 30 degrees C. to 150 degrees C.
