The significance of this work lies in the development of a novel code-based, detailed, and deterministic geometrical approach that couples the optimization of the Fresnel lens primary optical element (POE) and the dome-shaped secondary optical element ...

Defectoscopic Tests of Smoke Mortar Charges [PDF]
There are presented selected results of defectoscopic tests on smoke charges confined in the metallic containers inserted in the bodies of 98 mm mortar bombs, using Real Time Rentegenoscopy (RTR) and infrared (IR) thermography.

Optical transmission theory for metal-insulator-metal periodic nanostructures
A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layers with periodic one-dimensional ...

Predictive Modeling of Light–Matter Interaction in One Dimension: A Dynamic Deep Learning Approach
The mathematical modeling and the associated numerical simulation of the light–matter interaction (LMI) process are well-known to be quite complicated, particularly for media where several electronic transitions take place under electromagnetic ...

An ANN-Based Smart Tomographic Reconstructor in a Dynamic Environment
In astronomy, the light emitted by an object travels through the vacuum of space and then the turbulent atmosphere before arriving at a ground based telescope.

Optical-approximation analysis of sidewall-spacing effects on the force between two squares with parallel sidewalls [PDF]
Using the ray-optics approximation, we analyze the Casimir force in a two dimensional domain formed by two metallic blocks adjacent to parallel metallic sidewalls, which are separated from the blocks by a finite distance h.
