Effective-periodicity effects in Fibonacci slot arrays
(American Physical Society, 2021-12-29)
In this Letter, the transmission properties of a nonperiodic array of slots arranged in the form of a Fibonacci sequence are investigated. By arranging the slots in this manner, an additional periodicity can be utilized, ...

Engineering Casimir interactions with epsilon-near-zero materials
(American Physical Society, 2022-06-03)
In this paper, we theoretically demonstrate the tunability of the Casimir force both in sign and magnitude between parallel plates coated with dispersive materials. We show that this force, existing between uncharged plates, ...

A Lightweight Remote Attestation Using PUFs and Hash-based Signatures for Low-end IoT Devices
(Elsevier, 2023)
Remote attestation is a powerful mechanism that allows a verifier to know if the hardware of an IoT (Internet-of-Thing) device (acting as a prover) has been counterfeited or tampered with and if its firmware has been ...
