Holographic Aperture Antenna for Selectable RF Fields

The patent applies local quality by creating highly directional, localized electromagnetic fields that concentrate power transmission only in specific directions toward target devices. The holographic aperture enables different regions of the aperture to generate fields with specific spatial characteristics, allowing power to be delivered locally to intended recipients while minimizing radiation in directions where humans or other devices are present. This spatially selective field generation resolves the contradiction by improving power transfer efficiency to targets while reducing harmful exposure to bystanders.

The patent employs parameter changes by dynamically adjusting the amplitude and phase of electromagnetic fields across the holographic aperture elements. By controlling these parameters, the system can shape radiation patterns to maximize power delivery to target devices while minimizing exposure in other directions. The ability to independently control field parameters at each aperture element enables optimization of both power transfer efficiency and radiation safety simultaneously.

The patent applies dimensionality change by transitioning from conventional one-dimensional linear antenna arrays to two-dimensional holographic aperture arrays. This additional spatial dimension enables much greater flexibility in shaping radiation patterns and achieving arbitrary field distributions. The 2D aperture geometry provides more degrees of freedom for beamforming, allowing independent control of field amplitude and phase in multiple directions simultaneously, thereby greatly enhancing adaptability for various communication and power transmission scenarios.

The patent implements dynamics by enabling real-time, electronic reconfiguration of the holographic aperture's field-generating characteristics. Each aperture element can independently and dynamically adjust its amplitude and phase parameters, allowing the radiation pattern to be adaptively optimized for different target locations, environments, and operational requirements. This dynamic control capability provides versatile beamforming without requiring physical reconfiguration or increasing element density.
