  • Patent number: 12126100
    Abstract: An electromagnetic wave manipulation apparatus may include a substrate integrated with a liquid crystal. For example, the substrate may include one or more cavities filled with the liquid crystal. Alternatively and/or additionally, the substrate may include one or more layers of material interposed with the liquid crystal. The liquid crystal may be subjected to a voltage bias that alters the dielectric constant of the liquid crystal. Doing so may introduce a corresponding field offset between the input signal and the output signal of the apparatus. Subjecting the liquid crystal to different voltage biases may give rise to a spatial phase gradient that enables the apparatus to perform a variety of electromagnetic wave transformations such as reflection, refraction, retro-reflection, amplification, and cancellation. By performing such transformations, the apparatus may change the radiation pattern of its output signal, thus steering its output signal towards or away from a receiver.

  • Patent number: 12027760
    Abstract: An antenna system of a satellite may consist of an antenna receiver that is coupled to a plurality of flexible couplings. The couplings may each be affixed to one or more antenna elements. The couplings may be deployed in space in an uncontrolled manner. Additionally, the spacing between the couplings, and in turn the antenna elements, may be spaced in an uncontrolled manner. The antenna elements may have no pointing requirements. The antenna system may receive training signals and associate an antenna element to a time of arrival based on the training signal. Upon receiving a data signal, the antenna system may apply coefficients determined from the association of the antenna element to the time of arrival to the data signal to discover wanted signal coherence among the antenna elements.
