Area of Science:

• Nanotechnology
• Optics
• Materials Science

Background:

• Scattering efficiency in multilayered nanotubes impacts optical performance.
• Minimizing scattering is crucial for advanced photonic applications.

Purpose of the Study:

• To derive an optimization for multilayered nanotubes that minimizes scattering efficiency for a given polarization.
• To investigate the role of marginal layers in reducing scattering and achieving an invisibility effect.

Main Methods:

• Derivation of an optimization for cylindrical nanocavities with radially periodic distribution.
• Analysis of marginal layer configurations to reduce scattering efficiency.

Main Results:

• Scattering efficiency reduced by up to two orders of magnitude compared to previous designs.
