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 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. The holographic radar reflector can reflect electromagnetic radiation emitted from a fixed feed point in varying directions depending on the portion of the surface reflecting the electromagnetic radiation.

Abstract: Described embodiments include a system, apparatus, and method. A system includes an array of at least two groups of at least two artificially structured electromagnetic unit cells. Each group includes a controllable amplifier responsive to a B1 localization control signal and configured to amplify a received pulse of radiofrequency electromagnetic waves. Each group includes an electromagnetic wave conducting structure configured to deliver an amplified pulse of radiofrequency electromagnetic waves to the at least two artificially structured electromagnetic unit cells. The at least two artificially structured electromagnetic unit cells are configured to transform the incident amplified pulse into a pulse of radiofrequency magnetic field B1 orientated transverse to a segment of the z-axis. A control circuit selects an arbitrary examination segment transverse to the z-axis responsive to data indicative of a transverse slice selected for examination, and generates the B1 localization control signal defining an amplification state assigned to each group.

Abstract: The present disclosure is directed to systems for tuning nanocube plasmonic resonators and methods for forming tunable plasmonic resonators. A tunable plasmonic resonator system can include a substrate and a nanostructure positioned on a surface of the substrate. The substrate can include a semiconductor material having a carrier density distribution. A junction can be formed between the nanostructure and the substrate forming a Schottky junction. Changing the carrier density distribution of the semiconductor material can change a plasmonic response of the plasmonic resonator.
