Effect of Indoor Radio Propagation on Physical Layer Security Secrecy Key Generation

Physical Layer Security (PLS) is emerging as an innovative solution to enhance the security of wireless communications. This work analyzes the impact of a realistic indoor radio propagation on Secrecy Key Generation (SKG) in a WiFi application scenario. This PLS technique is based on the extraction of raw cryptographic keys, taking advantage of the radio propagation phenomena as a source of entropy. In detail, we considered two legitimate nodes, i.e., Alice and Bob, which use the SKG to extra...

Transparent polymeric metagrating for two-color reflection in augmented reality displays

This paper proposes a polymer-based transparent metagrating supporting multiple guided mode resonances in the visible spectrum. It achieves selective reflection of two colors simultaneously. This ability makes the metasurface promising for AR glasses, in assisting cognitively impaired individuals and for active and healthy aging.

Guided Mode Resonant Metagrating for Augmented Reality Lenses and Biosensing

This paper proposes a polymer-based metagrating supporting multiple guided mode resonances in the visible spectrum. It achieves selective reflection of two or more wavelengths simultaneously. This ability makes it promising for augmented reality metalenses and for biosensing applications.

Transparent Polymer-Based Metasurfaces for Augmented Reality Display

This work presents the design of transparent polymer-based metasurfaces that achieve selective color reflection through multiple guided mode resonances. This metasurface is promising for augmented reality (AR) applications, such as AR glasses and displays, helping people with cognitive impairments and encouraging active and healthy aging.

Fabry- Pérot cavity in SiN for non-linear applications

We present side-coupling Fabry-Pérot-based resonant mirror cavities in the 800 nm thick silicon nitride platform, implementing tapered and conventional Bragg grating. Experimental results highlight enhanced Q-factors and tunability, crucial for femtosecond hybrid laser generation.
