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.
