This study introduces perturbation-induced countersurveillance using meta-optics for secure information storage and covert exchange. The novel approach self-indicates attacks, enhancing data security for the Internet of Things.

Area of Science:

Meta-optics
Photonic materials
Nanophotonics

Background:

Meta-optics progress depends on identifying suitable photonic materials and geometries for desired optical functionalities.
Current material options are limited by natural availability, shifting focus to meta-atom geometry design.
Previous research overlooked perturbative meta-optics, viewing perturbations as detrimental.

Purpose of the Study:

To develop a perturbation-induced countersurveillance strategy for secure information concealment and exchange.
To explore the use of compound nanosieves and induced thermal-spectral drifts for covert communication.
To establish a self-indicating mechanism for detecting attacks on hidden information.

Main Methods:

Utilizing compound nanosieves mediated by structural and thermal perturbations.

Keywords:

Applied optics Nanophotonics and plasmonics Optical materials and structures
