TWO-DIMENSIONAL AND THREE-DIMENSIONAL DISCRETE CONSTRAINED LENSES WITH MINIMIZED OPTICAL ABERRATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240339764 titled 'TWO-DIMENSIONAL AND THREE-DIMENSIONAL DISCRETE CONSTRAINED LENSES WITH MINIMIZED OPTICAL ABERRATIONS
The abstract describes a beamforming network that includes a three-dimensional discrete lens with front and back apertures, each comprising discrete elements connected by transmission lines. The network can also include a feed array that illuminates the back aperture during transmission and receives signals from the back aperture during reception. The zooming factor, defined by the ratio of the back aperture size to the front aperture size, allows for the tilting of beam angles of electromagnetic radiation.
- Three-dimensional discrete lens with front and back apertures
- Homologous discrete elements in front and back apertures

Commercial Applications: Title: Advanced Beamforming Technology for Telecommunications and Radar Systems This technology can be utilized in telecommunications infrastructure, radar systems for defense and surveillance, satellite communication for data transmission, and other applications requiring precise beamforming capabilities.
Questions about Beamforming Networks: 1. How does the zooming factor affect the performance of the beamforming network? The zooming factor determines the angles at which beams of electromagnetic radiation are emitted or received, allowing for more precise control over signal directionality.
2. What advantages does a three-dimensional discrete lens offer over traditional beamforming methods? A three-dimensional discrete lens provides more flexibility and control in shaping and directing beams of electromagnetic radiation, leading to improved performance in signal transmission and reception.
Original Abstract Submitted
a beamforming network includes a three-dimensional discrete lens with front and back apertures, each comprising a plurality of discrete elements. each discrete element of the back aperture is homologous to a respective discrete element of the front aperture. the discrete lens further comprises a plurality of transmission lines connecting respective pairs of homologous discrete elements. the beamforming network can further include a feed array. the feed array illuminates the back aperture, when the lens is working in transmission, and/or receives signals from the back aperture, when the lens is working in reception. a ratio of a size of the back aperture and a size of the front aperture defines a zooming factor. the value of the zooming factor is different from unity, so that angles of emergence of beams of electromagnetic radiation emitted by the front aperture are either tilted towards a center axis of the discrete lens or tilted away from the center axis, compared to angles of incidence of corresponding beams on the back aperture.
