Macroscopic broadband optical escalator with force-loaded transformation optics.

Area of Science:

• Optics and Photonics
• Materials Science
• Metamaterials

Background:

• Transformation optics allows light control using metamaterials but lacks flexibility.
• Existing devices are deterministic and not adaptable to different objects or scenarios.

Purpose of the Study:

• To propose a novel force-induced transformational optical device.
• To demonstrate continuous metamorphosis between an optical elevator and an invisibility cloak.
• To enable dynamic and flexible light control without metamaterials.

Main Methods:

• Utilizing force-loaded transformation optics principles.
• Designing a schematic that is self-adaptive and multi-functional.
• Implementing directional force loading to control optical properties.

Main Results:

• The device achieves continuous transformation between an optical elevator and an invisibility cloak.
• It can visually alter perceived height or physically move an object while maintaining visual constancy.
• The device is adaptable, requires no background index change, and avoids metamaterial fabrication.

Conclusions:

• The force-induced transformational device offers dynamic and continuous light control.
• It presents a flexible alternative to deterministic transformation optics devices.
• Potential applications include military cloaking, optical communication, and holographic imaging.
