Goos-Hanchen-Shift Photonic Sensor for Nanometer-Scale Delayering and Tamper Detection in Semiconductor Packages
Mia Mohammad Shoaib Hasan, Mohamed Elkabbash
We propose a co-packaged photonic tamper sensor that detects progressive delayering and localized drilling through changes in the Goos-Hanchen (GH) shift of a reflected optical bea…

Observation of Light-Driven Levitation Near Epsilon-Near-Zero Surfaces
Maria Grazia Donato, Michael Hinczewski, Theodore Letsou +6
Optical manipulation of micro- and nanoparticles near surfaces is fundamental for applications in sensing and microfluidics, yet controlling particle-surface interactions remains c…

Inverse Drexhage effect in Epsilon-Near-Zero Substrates
Sandeep Kumar Chamoli, Mohamed ElKabbash
The Drexhage effect, caused by interference between a dipole and its image formed in a substrate, modifies the local density of optical states of quantum emitters which can either…
