摘要： An interleaved array of electronically steerable antennas is capable of simultaneously operating and/or independently beam scanning at different frequencies from a single aperture. An antenna system may comprise a plurality of electronically steerable antennas configured to be operable at different frequencies, each of the antennas comprising a feed launching a surface wave and surface-wave waveguides connected to the feed. The surface-wave waveguides of the antennas operable at different frequencies may be interleaved with each other.

摘要： A process enables growing thick stoichiometric crystalline and preferably IR- transparent optical PCMO material on Si and other substrates. Sputter deposition is carried out in oxygen-free inert gas (e.g., Ar) environment, which helps to prevent decomposition of the PCMO material over the substrate. In the disclosed process, there is no need to add a seed layer prior to PCMO deposition. Moreover, no post-deposition annealing is needed in a high-temperature and high-pressure oxygen furnace, but an anneal provides certain additional benefits in terms of improved transparency at IR wavelengths. Over a long deposition time for a thick PCMO film on the high temperature (≤450°C) substrates, the PCMO deposition is made repeated cycles of deposition of the PCMO material at the high temperature, each deposition cycle being followed by cooling the PCMO-deposited substrate to a substantially lower temperature (

摘要： Method and apparatus for converting electromagnetic surface waves from TE mode to TM mode and visa versa. Included is a dielectric surface having an anisotropic impedance tensor obtained by a plurality of electrically conductive unit cells disposed on the dielectric surface and arranged in a 2-dimensional array. A majority of the unit cells are divided into a least 2 portions. At least one gap separates the at least 2 portions from each other into 2 or more patches or plates. The array of unit cells has surface wave input and output ends; gaps in the unit cells disposed closest to the input end have a 1st orientation and gaps disposed closest to the output end have a 2 nd orientation different than the 1 st . The electromagnetic surface waves have a frequency greater than a TE cutoff frequency determined by a second solution of Maxwell's equations for said dielectric surface.

摘要： An optical apparatus may comprise: an electrically reconfigurable optical layer comprising at least one phase-change material, wherein an optical property of the phase-change material is reconfigurable by an electric field; an optically transparent top electrode and a bottom electrode, the top and bottom electrodes configured to apply the electric field to the electrically reconfigurable optical layer, wherein the electrically reconfigurable optical layer is disposed between the optically transparent top electrode and the bottom electrode; and a colossal-K dielectric layer disposed between the electrically reconfigurable optical layer and the bottom electrode. The phase-change material of the electrically reconfigurable optical layer may comprise phase-change nickelate or tungsten oxide. The phase-change material of the electrically reconfigurable optical layer may have a perovskite structure. The phase-change nickelate or tungsten oxide may enable to actuate large refractive index changes of more than 1 in infrared wavelength spectrums at high speeds of phase reconfiguration of more than 1 kHz by applying the electric field to the phase-change material.
