SYSTEM AND METHOD DESIGNING METALENS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17994127 titled 'SYSTEM AND METHOD DESIGNING METALENS

Simplified Explanation

The patent application describes a system and method for designing a metalens with nanostructures and a spacer layer. Here are the key points:

  • The system selects a design area based on the width and pitch of the nanostructures.
  • A search route is set in the design area, following a direction where the phase decreases.
  • Transmittance is calculated at a reference point and change points along the search route.
  • The width and pitch of the nanostructures are determined based on the calculations.
  • A phase map is generated to represent the width and pitch of the nanostructures.
  • The system extracts the width and pitch that correspond to a target phase from the phase map.
  • The nanostructures with the extracted width and pitch are placed in the metalens to achieve the target phase.

Potential applications of this technology:

  • Optical devices: The metalens design can be used in various optical devices, such as cameras, microscopes, and telescopes.
  • Communications: The metalens can be applied in optical communication systems to enhance signal transmission and reception.
  • Sensors: The metalens design can improve the performance of sensors used in industries like healthcare, environmental monitoring, and manufacturing.

Problems solved by this technology:

  • Design optimization: The system provides a method to optimize the design of metalenses by calculating transmittance and extracting the desired width and pitch.
  • Phase control: The technology allows precise control of the phase in the metalens, enabling better focusing and manipulation of light.
  • Efficiency improvement: By optimizing the design, the metalens can achieve higher efficiency in light transmission and manipulation.

Benefits of this technology:

  • Enhanced performance: The metalens design improves the performance of optical devices, sensors, and communication systems by optimizing the phase control.
  • Compact size: Metalenses can be made smaller and thinner compared to traditional lenses, allowing for more compact and lightweight devices.
  • Versatility: The system's design approach can be applied to various applications and can be customized for different target phases.
