Equivalence of Optical Theorems
Edwin A. Marengo, Mohammadrasoul Taghavi
We demonstrate, in the full vector formulation of electromagnetic fields, that the well-known optical theorem pertinent for the characterization of a scatterer's extinction power a…

Differential Sensing Approaches for Scattering-Based Holographic Encryption
Mohammadrasoul Taghavi, Edwin A. Marengo
We develop a new scattering-based framework for the holographic encryption of analog and digital signals. The proposed methodology, termed "differential sensing", involves encrypti…
