Abstract: Subwavelength conducting particles can be arranged on conducting surfaces to provide arbitrary thermal emissivity spectra. For example, a thermal emissivity spectrum can be tailored to suppress a thermal signature of an object without sacrificing radiative cooling efficiency.

Abstract: A beamforming system, comprising a plurality of subsets of tunable resonator elements arranged on a substrate. Each subset of tunable resonator elements comprises at least two resonator elements that have a common resonance property modifiable by a common physical stimulus. A first control input may provide a first physical stimulus to modify the resonance property of all the tunable resonator elements in a first subset of tunable resonator elements. A second control input may provide a second physical stimulus to modify the resonance property of all the tunable resonator elements in a second subset of tunable resonator elements. A controller adjusts the first and second physical stimulus provided via the control inputs between a plurality of physical stimulus values. Each different physical stimulus value corresponds to one of a plurality of a unique resonance patterns and associated unique radiation patterns.

Abstract: The present disclosure provides systems and methods associated with mode conversion for electromagnetic field modification. A mode converting structure (holographic metamaterial) is formed with a distribution of dielectric constants chosen to convert an electromagnetic radiation pattern from a first mode to a second mode to attain a target electromagnetic radiation pattern that is different from the input electromagnetic radiation pattern. A solution to a holographic equation provides a sufficiently accurate approximation of a distribution of dielectric constants that can be used to form a mode converting device for use with one or more transmission lines, such as waveguides. One or more optimization algorithms can be used to improve the efficiency of the mode conversion.

Abstract: A 2D hologram system with a matrix addressing scheme is provided. The system may include a 2D array of sub-wavelength hologram elements integrated with a refractive index tunable core material on a wafer substrate. The system may also include a matrix addressing scheme coupled to the 2D array of sub-wavelength hologram elements and configured to independently control each of the sub-wavelength hologram elements by applying a voltage.

Abstract: A holographic radar reflector includes a surface with a plurality of substantially microwave wavelength scale patterns along one or more portions of the surface. The holographic radar reflector can be a non-specular reflector, where the plurality of substantially microwave wavelength scale patterns have varying reflectivity.
