Mid-wavelength infrared (MWIR, λ = 3 – 5 μm) materials are of great importance due to their applications in optical sensors and devices for military, industry, and non-invasive medical diagnostics. Specifically, MWIR polarimetry are used in biome

This study introduces a method to predict the refractive index (RI) of nanocomposites with the Finite Elements Analysis (FEA) based on the Fabry-Perot interference. The efficacy was verified by comparing the estimated composites’ RI with the availa

Organically modified chalcogenide (ORMOCHALC) polymers have proven to be alternatives to the conventional inorganic materials for mid-wavelength infrared (MWIR, λ = 3–5 μm) optical components. While the refractive index of ORMOCHALC can be reinfo

Metamaterials have been shown to exhibit frequency and spatial dispersion. (A. Alu, arxiv.org/ftp/arxiv/papers/1012/1012.1351.pdf) In a frequency and spatially dependent medium the permittivity (e(ω, k)) and permeability (μ(ω, k)) are dependent on

We report a RF and IR data-integration strategy based on a probabilistic (or a distribution) model. At the heart of our approach is the ability to extract the probability density functions (pdfs) from the sensed dataset for RF and IR respectively fol
