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…
Optical-Theorem-Based Holography For Target Detection and Tracking
Mohammadrasoul Taghavi, Edwin A. Marengo
The development of robust, real-time optical methods for the detection and tracking of particles in complex multiple scattering media is a problem of practical importance in a numb…
Dynamic Scattering-channel-based Approach for Multiuser Image Encryption
Mohammadrasoul Taghavi, Edwin A. Marengo
Conventional scattering-based encryption systems that operate based on a static complex medium which is used by all users are vulnerable to learning-based attacks that exploit ciph…
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…
